Donovanosis is a rare, chronic and indolent sexually transmitted infection caused by Klebsiella granulomatis. The ulcers in donovanosis rarely undergo malignant transformation, which is usually seen in longstanding ulcers. We present a case of a 32-year-old male who presented with a two-month history of rapidly progressive, large, foul-smelling ulcers over the groin, distal penile shaft and scrotum. Crushed tissue smears from ulcers revealed basophilic intracellular and extracellular Donovan bodies. Fine needle aspiration cytology from inguinal lymph nodes and biopsy from the ulcers revealed well-differentiated squamous cell carcinoma. The current case aims to alert clinicians that donovanosis is a rare but possible cause of cutaneous malignancy. Nonetheless, the pathogenesis of malignant transformation in donovanosis needs further research.

A 45-year-old farmer presented with ulcers and plaques over his scrotum for the past 4 to 5 years. The condition started as a small lesion on the shaft of the penis, which improved with treatment; however, after 2 to 3 months, papulonodular lesions developed on the scrotum, which increased in size and subsequently broke down to form ulcers. He denied drug abuse but had a history of multiple unprotected sexual exposures. He was prescribed oral antibiotics, which improved the lesions, but he failed to take the antibiotics for more than a week. He also used powders, lotions, and salves (exact nature not known), which did not help and sometimes even burned the skin. After stopping the medicine, he developed new lesions that followed a similar course. Examination revealed nontender ulcers on the scrotum with raised, rolled-out margins and pale red, granulation tissue that bled on touch (Figure 1). In addition, there were nodules with a pinkish red granular surface and scaly erythematous plaques on the scrotum. Regional lymph nodes were not enlarged.

Granuloma inguinale, or Donovanosis, is a rare, sexually transmitted ulcerative disease primarily affecting the genital area. In this report, we present a case of a 50-year-old man that was diagnosed with granuloma inguinale after a 2-month history of a penile ulcer. Histological analysis demonstrated the presence of Donovan bodies within macrophages, confirming the diagnosis. He was subsequently treated with trimethoprim/sulfamethoxazole with improvement in the ulcer. This case serves as a reminder to clinicians that although granuloma inguinale is rarely encountered in the US, it should still be suspected in patients with non-healing penile ulcers.

Donovanosis causes granulomatous ulceration of genitalia and neighbouring sites with little tendency to heal spontaneously. It is uncommonly seen nowadays in sexually transmitted infection clinics of north India. The present case is reported for its scarcity and to make clinicians aware of this disease which may rarely accompany carcinoma., (© The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.)

Two infants, 6 months and 4 months of age, presented with bilateral or unilateral external auditory canal polyps and otorrhea, respectively. Additional findings on examination included otitis media and mastoiditis. Tympanic membrane perforation was noted in one patient and a postauricular abscess in the other. Incisional biopsies of the polyps and abscess were reported as nonspecific mixed inflammation and abscess wall, respectively. There was a limited response to an empirical 5-day course of trimethoprim sulfamethoxazole. The children were referred to the academic hospital, and excision of the polyps and biopsies of the middle ear, mastoid, and postauricular abscess was undertaken. All the biopsies demonstrated donovanosis. Reappraisal of the initial incisional biopsies also confirmed donovanosis. Trimethoprim sulfamethoxazole was administered to both patients for 3 weeks, with resolution of the lesions. Subsequent investigations confirmed genital tract donovanosis, human immunodeficiency virus seropositivity, acquired immunodeficiency syndrome, and pulmonary tuberculosis in both mothers. Heightened awareness of the occurrence of donovanosis at unusual sites and improved recognition of the histomorphological features of the disease, especially in small and superficial biopsies, are pivotal not only for its correct diagnosis in extragenital cutaneous and extracutaneous locations but also for timely and adequate therapy and an improved infant and maternal outcome.

Genital elephantiasis is a disease that is characterized by massive enlargement of the genitalia. Early aetiological diagnosis is of paramount importance so that development of genital elephantiasis can be prevented; otherwise it is not completely reversible with medical therapy and often requires surgical intervention. Chronic mental distress and disability can result as it interferes with daily/routine activities of the affected individual. Over time, the infectious causes of genital elephantiasis have evolved, from syphilis in the pre-penicillin era to donovanosis, lymphogranuloma venereum and recently filariasis, tuberculosis, leishmaniasis, HIV and chromoblastomycosis. With a declining prevalence globally, donovanosis is at risk of being forgotten as a cause of genital swelling; however, it is known to persist for years without treatment and can lead to complications such as lymphoedema and genital mutilation. We herein present a case of genital elephantiasis that was eventually diagnosed as being due to donovanosis.

A 46-year-old man complained of ulcerovegetative lesions in the anogenital region, which he had noted one month prior to presentation. The patient had a history of travel to African countries. Therefore, the ulcerovegetative lesions of the patient were suspected to be granuloma inguinale (GI). Calymmatobacterium granulomatis was not observed in the direct examination of scrapings collected from the base of the ulcerovegetative lesion. Instead, a histological examination revealed cutaneous metastasis of mucinous adenocarcinoma of the rectum. Therefore, a diagnosis of GI was eliminated. As the patient did not report his history of rectal cancer and had travelled to African countries, we had primarily focused on the diagnosis of GI.

The authors present images of two of the most common clinical forms of granuloma inguinale (donovanosis) in males and females. Donovanosis is considered a sexually transmitted disease that is endemic in tropical and subtropical regions of the world. Two microscopic images are also shown, one of a direct smear (the presence of Donovan bodies within large mononuclear cells identified using Giemsa stain) and the other of typical histological findings (rod-shaped Donovan bodies within a mononuclear histiocyte).

Donovanosis is a rare sexually transmitted infection now mainly seen in sporadic cases in Papua New Guinea, South Africa, India, Brazil and Australia. The causative organism is Calymmatobacterium granulomatis though a proposal has been put forward that the organism be reclassified as Klebsiella granulomatis comb. nov. The incubation period is approximately 50 days with genital papules developing into ulcers that increase in size. Four types of lesions are described - ulcerogranulomatous, hypertrophic, necrotic and sclerotic. The diagnosis is usually confirmed by microscopic identification of characteristic Donovan bodies on stained tissue smears. More recently, polymerase chain reaction (PCR) methods have been developed. The recommended treatment is azithromycin 1 g weekly until complete healing is achieved.

Donovanosis is endemic in various parts of the world. Although donovanosis has been reported to co-exist with the human immunodeficiency virus (HIV) infection, to our knowledge there have been no reports of co-existent squamous cell carcinoma (SCC) in an HIV positive patient. In our case the patient did not respond to treatment for donovanosis and on biopsy we realized that the patient had coexistent SCC, which is hitherto unreported with granuloma inguinale.

A 23-year-old male presented with oral ulcers. Tissue smear showed Donovan bodies. The patient was treated with oral tetracycline.

Donovanosis is a sexually transmitted infection which presents with genital ulceration and inguinal lymphadenopathy. Rarely, it presents with extra-genital manifestations. We present a case of disseminated donovanosis with cervical ulceration, massive pelvic lymphadenopathy, osteomyelitis of the wrists and septic arthritis of the knees and right elbow. A 23-year-old gravida two presented with wasting, oedema, ascites, bilateral iliac lymphadenopathy, anaemia and a large ulcer of the cervix uteri. Two months later in the outpatient clinic, she was much improved but still had post-coital bleeding and a hyperaemic cervix, suggestive of persistent infection. The course of antibiotics was therefore repeated. Histopathological examination of a specimen from colposcopic biopsy of the cervix uteri revealed granuloma inguinale. She improved after several courses of antibiotics, blood transfusion, surgical débridement and aspiration of affected joints.

We present a case of a 39-year-old woman with a vulval lesion, which macroscopically looked consistent with a fungating squamous cell carcinoma of the vulva. However, further investigations demonstrated a less common cause for this presentation.

Background: Transepithelial elimination (TEE), a distinct and well-known entity, is a process during which the skin eradicates undesirable or irritative dermal substances through intact epidermis or follicular epithelium by passive or active means. Although TEE is being described in an increasing number and range of pathological processes, to date, TEE of granuloma inguinale (GI) remains unrecorded in the English-language literature. The aims of this study were: 1) To appraise the light microscopic and ultrastructural morphological epidermal changes that are associated with TEE of cutaneous vulval GI; and 2) To determine the role of intra-epidermal leucocytes and histiocytes in the pathogenesis of TEE of vulval GI., Methods: This is a retrospective 9-year histopathological review of all cases diagnosed and coded as vulval granuloma inguinale in the Department of Anatomical Pathology, Nelson R. Mandela School of Medicine, University of Natal, Durban, South Africa. Ultrastructural evaluation was performed on selected cases using a Jeol transmission electron microscope., Results: Of 53 skin biopsies from 47 patients with vulval GI, 43 were suitable for the study. The age range of patients was 15-40 years (mean age=22 years). There were eleven papular, twelve nodular, seven verrucous and thirteen ulcerative lesions. Donovan bodies within macrophages, free-lying Donovan bodies and dense aggregates of neutrophils and plasma cells were seen in the dermis of all biopsies. There was consistent overlying pseudoepitheliomatous hyperplasia. The dermal inflammatory infiltrate hugged the dermo-epidermal junction and appeared entrapped between elongated and acanthotic epidermal rete ridges and pegs. Transepidermal neutrophil microabscesses, histiocytes containing Donovan bodies and neutrophilic and histiocytic fragmentation were present. A variable number of free-lying and intra-histiocytic Donovan bodies and neutrophils were present on the surface of the epidermis. On ultrastructural investigation epidermal spongiosis, intracellular oedema, free-lying, intra-neutrophilic and intra-histiocytic Donovan bodies, and intact and degenerating neutrophils and histiocytes were evident between keratinocytes. The degenerative histiocytes demonstrated marked vacuolation, mitochondrial swelling and bacilli within phagolysosomal vacuoles, bound by intact or disrupted limiting membranes., Conclusion: The inflammatory infiltrate at the epitheliomesenchymal interface, pseudoepitheliomatous hyperplasia, intra-epidermal accumulation and disintegration of neutrophils and histiocytes, and the associated release of lytic enzymes, play important contributory roles in TEE of GI. TEE of infectious agents is a poorly recognised mechanism of spread of infectious diseases and represents a public health hazard. In cutaneous vulval GI, TEE is highlighted as a hitherto unrecognised, potential method of spread of Calymmatobacterium granulomatis.

A case of granuloma inguinale (GI) presenting as a lateral neck mass in a 4-month-old, HIV-positive infant is described. The histological features of the mass were typical of GI, with numerous macrophages containing intracellular organisms with a "closed-safety-pin" appearance. This is a rare occurrence, and the mode of transmission of infection is discussed. An awareness of GI in infants by both clinicians and pathologists is important to prevent morbidity and allow for prompt institution of appropriate treatment.

The ultrastructural features of cells of Calymmatobacterium granulomatis from monocyte co-cultures and tissue biopsy specimens were compared. In cultures the bacteria were mainly extracellular, i.e., not within membrane-bound vacuoles. The bacterial body was surrounded by a uniformly extensive homogeneous layer with a relatively high electron density. This layer varied considerably in tissue biopsy specimens, having either homogeneously electron-dense or delicate web-like structures with varying density and thickness. In tissue specimens the bacteria were located predominantly within vacuoles of varying sizes in the cytoplasm of the macrophages and, occasionally, extracellularly within the intercellular spaces of the stroma. The bacterial cytoplasm contained ribosomes scattered throughout with electron-dense granules located peripherally. The trilaminar cell-wall structure was typical of a gram-negative organism, comprising an outer membrane, a middle electron-opaque layer and an inner plasma membrane. Surface structures such as fimbriae, flagella and bacteriophages were not identified in specimens from either source.

Donovanosis is a genital ulcer disease that occasionally has extragenital manifestations. This report describes a case of disseminated donovanosis in a 54-year-old woman from northern Australia who had subsequent thoracic vertebral osteomyelitis and spinal cord compression. Malignancy and vertebral tuberculosis were the major differential diagnoses. The patient had no genital lesions at the time of diagnosis of extragenital donovanosis but had undergone a hysterectomy, thus raising the possibility of prior disease of the uterine cervix (most previous cases have been associated with primary cervical disease). Despite treatment with doxycycline, she had no significant neurological improvement. Donovanosis disseminated to bone has been reported in 18 cases in the last 55 years. Awareness of donovanosis in the differential diagnosis of osteomyelitis and prompt pelvic examinations enabling early diagnosis of occult cervical disease are the most important measures in preventing morbidity and mortality due to disseminated donovanosis.

Granuloma inguinale (donovanosis) is seen predominantly in adults (it rarely occurs in children) and mainly affects genital skin and mucosa. Infection occurs at other skin and mucosal sites, and hematogenous dissemination to bone also has been described. The infection responds dramatically to appropriate antibiotic treatment. We present two cases of granuloma inguinale occurring in children (8 months and 5 months of age) causing mastoiditis and external ear discharges. A temporal lobe abscess also developed in the 8-month-old child. Subsequent computed tomography scans showed marked improvement in the brain lesion after treatment. The second child had a polypoid mass in the middle ear that on biopsy showed the features of granuloma inguinale. The mother of this child had biopsy-proven granuloma inguinale of the uterine cervix. These cases indicate that granuloma inguinale can be transmitted during vaginal delivery, and careful cleansing of neonates born to infected mothers is recommended.

We report successful culture of Calymmatobacterium granulomatis by standard cell culture methods. Swabs were obtained from lesions in three patients with a clinical diagnosis of donovanosis. For two patients, there was histological confirmation of the disease (i.e., the presence of Donovan bodies in Giemsa-stained smears). Specimens were inoculated onto cycloheximide-treated HEp-2 cell monolayers in RPMI 1640 medium (supplemented with fetal calf serum, NaHCO3, vancomycin hydrochloride, and benzylpenicillin). At 48 h, organisms resembling Donovan bodies were identified in monolayer cultures from all three specimens. The organisms appeared as pleomorphic bacilli with characteristic bipolar staining and "safety pin" appearance. Using a PCR designed to differentiate C. granulomatis from the Klebsiella species (which have a high degree of molecular homology), we were able to demonstrate that the cultured organisms produced a PCR product identical to that obtained from the original swab specimens. It is now possible to test in vitro susceptibility of C. granulomatis to antibiotics and to provide a ready source of DNA and antigenic material to enable the development of serological tests and, possibly in the future, a vaccine.

Donovanosis (Granuloma inguinale) is an infectious disease, the effects of which are usually confined to the genital region. Various extragenital manifestations of the disease have been described. This report describes a case where the condition represented in the oral cavity some time after the apparently successful treatment of the genital lesion. Members of both the medical and dental profession serving the northern parts of Australia and adjacent tropical regions should be aware of the possibility of encountering this disease. Delay in its diagnosis may result in extensive tissue destruction and a potentially fatal outcome. Intensive antibiotic therapy followed by long-term follow-up is usually curative.

Granuloma inguinale (GI) is a sexually transmitted disease seldom seen in the United States and Canada. We are reporting three cases recently seen in Toronto, Ontario, two in immigrants, and one in a native born Canadian who had an intimate relationship with a foreign visitor. The basic features of the disease are discussed.

Sexually transmitted disorders may present on the vulva as ulcers, rashes, edema, adenopathy, or pruritus. Clinical and laboratory skills are needed to distinguish one from another so that the proper treatment is selected and further venereal spread is prevented.

Donovanosis is a predominantly tropical cause of genital ulcer occurring chiefly in small endemic foci in all continents except Europe. Diagnosis requires the careful collection, staining and examination of smears or biopsies of characteristic genital and, occasionally, extragenital lesions for demonstration of the pathognomonic Donovan bodies (Calymmatobacterium granulomatis) within histiocytes. Successful isolation of C. granulomatis has rarely proved feasible, the last report being in 1962. Donovanosis has a characteristic histopathological picture which occasionally simulates epithelioma. The antibiotics reported as showing good activity in donovanosis are those with good activity against gram negative bacilli and whose lipid solubility ensures good intracellular penetration. They include streptomycin, chloramphenicol, erythromycin, lincomycin, cotrimoxazole and the tetracyclines. More recently, good results have been reported with norfloxacin and thiamphenicol. The treatment of donovanosis in pregnant women and patients with AIDS poses special problems. Complications of donovanosis such as elephantiasis, stricture and pelvic abscess may require surgery. Contacts should be traced for examination but only treated if lesions are found.

Total T-, B-, T4-, and T8-lymphocyte populations were estimated in tissue sections of ulcers from 22 donovanosis patients, comprising 17 ulcerogranulomatous, four hypertrophic, and one sclerotic variants, using monoclonal antibodies and immunohistochemical technique (PAP). T- and B-lymphocytic infiltrations in the tissues were almost identical, without any significant difference in ulcerogranulomatous and hypertrophic variants. The T4:T8 ratio in ulcerogranulomatous variants, however, was 1.41, which was significantly higher than that of hypertrophic variants (1.28), indicating a greater cell-mediated immune response in the former than in the latter. This is substantiated by the documentation of a paucity of Donovan bodies, both in the tissue smear and slow (overnight) Giemsa-stained tissue sections, in the ulcerogranulomatous variant.

Granuloma inguinale of the cervix presents as a proliferative growth and may mimic carcinoma. Over a 3 year period 18 patients with cervical granuloma inguinale were detected. Nine (50%) had a clinical diagnosis of carcinoma of the cervix on admission, five of whom had extensive investigations to exclude a malignancy. In communities where these two conditions are commonly seen it is recommended that granuloma inguinale be considered in young women with granulomatous lesions of the cervix, so as to avoid extensive and financially costly investigations, and unnecessary psychological stress for patients.

Granuloma gluteale infantum, a benign granulomatous eruption involving the gluteal region, histologically shows a nonspecific dermal inflammatory infiltrate composed of neutrophils, lymphocytes, histiocytes, plasma cells, and eosinophils. It is important to recognize this condition, as it may clinically simulate a neoplastic process. It arises as a complication of primary irritant diaper dermatitis, however, and typically resolves without treatment.

A 63-year-old Hispanic man from Peru who recently had immigrated to the United States presented with progressive weakness, weight loss, recurrent abdominal pain and passing bright red blood per rectum. Rectal carcinoma was suspected. Biopsies of two lesions in the sigmoid colon showed granuloma inguinale (donovanosis). A computed tomographic scan of the abdomen revealed a large presacral mass. A radiographically guided fine needle aspiration (FNA) of the presacral mass showed findings characteristic of granuloma inguinale. FNA thus proved to be a useful adjuvant in the diagnosis of an unusual case of granuloma inguinale (donovanosis) presenting with a presacral mass that had the radiologic characteristics of a malignant tumor.

Granuloma inguinale has been reported to mimic squamous cell carcinoma, as well as sexually transmitted diseases. We describe a rare case of extragenital granuloma inguinale that mimicked a soft tissue neoplasm in an 18-year-old pregnant woman who presented with cervical and labial ulcers. An elective cesarean section was performed, at which time a retroperitoneal mass that involved the right ureter was found. At frozen section, the mass had a xanthogranulomatous appearance consistent with a soft-tissue neoplasm. Special stains of the permanent sections revealed the pathognomic features of granuloma inguinale.

Pseudoelephantiasis of the penis, an unusual sequel of longstanding donovanosis with otherwise characteristics clinical expression, is reported in a young man. The diagnosis was confirmed by the demonstration of Donovan bodies in Giemsa stained tissue smears and tissue sections.

The cytologic findings in two histologically confirmed cases of granuloma inguinale are presented. The Papanicolaou staining method used in routine cytology screening proved to be suitable for the detection of the characteristic Donovan bodies in smears of the vulvar lesions.

Donovanosis (granuloma inguinale), a disease often related to sexual contact, has been a clinical problem in Papua New Guinea for more than 9 decades. It is a common cause of anogenital lesions in females in this country. Lesions on the cervix or vaginal vault, and extension of the disease process from the external genitalia to the uterus, tubes and ovaries, are thought to be rare. In this study an attempt was made to discover the frequency of involvement of cervix, uterus and adnexae, with or without external genital involvement, by retrospectively analyzing the histological and clinical records of patients with anogenital donovanosis for a period of 8 years (1975-1982). In 35 of 351 patients (10%), donovanosis involved the cervix. The clinical profile of these cases, certain unusual features in a few cases, and the pathological findings are discussed.

The role of histopathology in the diagnosis of donovanosis was assessed in 42 patients. There was heavy infiltration of the dermis with plasma and mononuclear cells but with few lymphocytes and neutrophils. The epidermis contained focal collections of polymorphoneuclear leucocytes. Endothelial proliferation and dilation of dermal blood vessels was striking. Intracellular and extracellular Donovan bodies were shown in Giemsa stained sections from 40 patients. Pseudoepitheliomatous hyperplasia was found in biopsy specimens from a few patients.
