We report an atypical presentation of a current disease to highlight the importance of making a correct diagnosis of scabies surrepticius in front of any itchy dermatosis especially in elderly patients. The misdiagnosis of this disease results in extensive infestation, especially with the use of corticosteroids.

La fibromatose mammaire est une tumeur mammaire bénigne d´origine mésenchymateuse, elle représente 0.2% des tumeurs du sein. Cet article relate deux observations de fibromatose mammaire étayant ses particularités diagnostiques, morphologiques, thérapeutiques et évolutives. Dans les deux cas, la tumeur mime sur le plan clinique et radiologique un cancer. La confirmation diagnostique est obtenue par une preuve histologique. La fibromatose mammaire se caractérise par une évolution locale et une tendance à la récidive, d´où l´intérêt de l´exérèse chirurgicale avec marges saines obtenues chez nos patientes. La place des traitements locorégionaux (la radiothérapie et la cryothérapie) et des traitements médicaux, en particulier les anti-estrogènes n´est pas clairement définie. En conclusion, la fibromatose mammaire doit être connue puisqu´elle mime en tout point un cancer de sein et se caractérise par un taux de récidive très important sans jamais donner de métastases.

Introduction and importance Histiocytic sarcoma (HS) is a rare malignant neoplasm showing morphologic and immunohistochemical features of histiocytes. It is characterized typically by extranodal presentation and a poor clinical course, particularly in cases with disseminated disease. Case presentation This report documents a case of bifocal and aggressive HS in small bowel and lung revealed by acute peritonitis in a 63-year-old man. Clinical discussion Despite its rarity, we believe that the correct diagnosis of HS is crucial for clinical treatment and prognostic prediction. Conclusion The collection of additional cases of HS are important to obtain further progress in prognosis and guide treatment decisions., Highlights • Histiocytic sarcoma is a rare malignant neoplasm showing morphologic and immunohistochemical features of histiocytes. • The diagnosis of histiocytic sarcoma can be extremely challenging because histologic overlap with diverse mimics. • Judicious application of immunohistochemical markers is crucial to confirm the diagnosis. • The collection and evaluation of additional cases are pivotal to obtain further progress in prognosis and guide treatment decisions.

Introduction and importance The ossifying fibromyxoid tumor of soft tissue is a rare tumor of intermediate differentiation and uncertain lineage that occurs in adults mostly in the extremities and the trunk. Presentation of case we present a case of 57 year-old man presenting with a right scapular mass. It was a subcutaneous and painless mass that was largely excised. The diagnosis of ossifying fibromyxoid tumor of the right shoulder was made. The follow up of 1 year was without recurrence and metastasis. Clinical discussion The ossifying fibromyxoid tumor of soft tissue is exceptional, microscopic diagnosis and management is challenging, considering the scarcity of the tumor. Conclusion More cases and retrospective studies are needed to understand the pathogenesis and to determine optimal treatment regimens., Highlights • Clinical, gross and microscopic examinations of ossifying fibromyxoid tumor.

Inverted papilloma is a rare nasosinusal tumor that mainly occurs in adults during the 5th decade. The occurrence in children is exceptional and only few cases have been reported in the litterature. Clinical and radiological findings mimic other benign nasosinusal pathologies; therefore, diagnosis is based on histopathology either via biopsy or following surgical excision. Here we present a rare case of pediatric inverted papilloma in a 11-year-old child and we discuss clinical, radiological, therapeutic and evolutionary features through a literature review.

Bullous morphea is a rare variant of localized scleroderma characterized by occasional intermittent blisters. Lichen sclerosus is a chronic inflammatory disease. The coexistence of morphea and lichen sclerosus has been reported in different sites in the same patient and more rarely in the same lesion. We report the case of a 54-year-old woman with an atypical presentation of bullous morphea and some histological features of lichen sclerosus. She presented with a 5-year history of an ulcerated plaque, with a sclerotic and atrophic center and indurated budding margins, localized on the lumbar back. Initially the diagnosis of a squamous cell carcinoma was suggested. A skin biopsy confirmed the diagnosis of bullous morphea and showed some histological features of lichen sclerosus. Topical betamethasone and silicone gel ointment were prescribed leading to complete healing of the ulceration within five months. Our case is unusual because of the atypical clinical presentation, the histological aspect combining signs of bullous morphea and lichen sclerosus, and the favorable results with the use of local corticotherapy and silicone gel.

This study was aimed at investigating the chemical composition (proximate, minerals, fatty acids and phenolic compounds) and the in vitro (antimicrobial, radical scavenging, anti-acetylcholinesterase and protein denaturing activities) and in vivo (anti-diabetic and histo-protective effects in alloxan-induced diabetic mice) biological activities of broad bean pods (BBPs), a food waste by-product material. The results showed that BBPs have high dietary fiber (57.46%), carbohydrate (18.93%) and protein (13.81%) content versus low fat content (

L'osteogenese imparfaite (OI) est un groupe heterogene de maladies affectant le collagene de type I et caracterisees par une fragilite osseuse. Les formes letales sont rares et se caracterisent par une micromelie avec deformation des membres. Un diagnostic antenatal d'OI letale a ete fait dans deux cas, par echographie a 17 et a 25 semaines d'amenorrhee, complelees par un scanner du squelette fœtal dans un cas. Une interruption therapeutique de grossesse a ete indiquee dans les deux cas.

Li Fraumeni Syndrome (LFS) is a rare autosomal disorder characterized by a familial clustering of tumors. Analysis of several series of LFS families have shown that 70% of such families are attributable to germ-line mutations in TP53. We report the case of a patient who had a first degree family antecedent of cancer in young ages. At the age of 31 years, the patient was operated of bladder papillary superficial carcinoma; five years later, he was treated for a high grade pleomorphe sarcoma of the left thigh and treated by surgery, adjuvant chemotherapy and radiotherapy. At the age of 38 years, after abdominal pain, radiologic examination reveled pancreatic tumor with bone and lymphatic metastases. The patient died one month later from pulmonary embolism. Sequencing revealed a germiline mutation of this patient that was confirmed in a member of his family in codon 1009C>T, protein Arg337Cys, exon 10 of TP53 gene this mutation was revealed in his nephew (died at the age of 20 from bone sarcoma).

Epithelial ovarian tumors are uncommon before 20 years of age and rarely occur before puberty. The vast majority of these tumors are benign, and few cases of malignant and borderline tumors are described. We report a case of a 4-year-old premenarchal girl, previously healthy, who presented with two abdominal masses. Laboratory analysis of blood showed elevation of the serum level of the CA-125. Ultrasonographic examination disclosed bilateral cystic ovarian masses. Laparoscopic exploration revealed bilateral ovarian multicystic masses with retro-uterine peritoneal implant. Bilateral salpingo-oophorectomy with implant resection was performed. Histologic findings were consistent with a serous borderline tumors of both ovaries and the peritoneal implant was of the non-invasive type. There is no evidence of recurrence at 3-year follow-up. To our knowledge, there are only four cases of ovarian borderline tumors in premenarchal girls reported in the English literature: three of the mucinous type and only one of the serous type.

Lipoblastoma is a rare, benign, fatty tissue tumor that occurs in childhood. The location of this tumor in the mediastinum and extension to the chest wall is uncommon. We describe a 12-month-old male infant with a mediastinal lipoblastoma discovered because of a chest wall swelling. Computed tomography showed the deep component and fatty content of the lesion suggestive of the diagnosis. Total excision of the mass was carried out. The histologic examination of the lesion confirmed the diagnosis of lipoblastoma. Mediastinal lipoblastoma should be considered among the possible diagnoses of a fatty mediastinal tumor in childhood.

An infant with congenital pancreatic cyst with Ivemark II syndrome is reported because it is a rare association. The infant had associated situs inversus, asplenia, and complex congenital heart disease. The pancreatic cyst was successfully managed by cystoduodenostomy because of connection to the biliary tract. The infant succumbed as a result of heart failure at age 2 months. Prognosis depends on the presence of life-threatening malformations.

Merkel cell carcinoma (MCC) or primary neuroendocrine carcinoma of the skin is a rare neoplasm with aggressive behavior. Primary lymphoepithelioma-like (LEL) carcinoma of the skin is a recently described exceptional tumor, with a relatively good prognosis, and is characterized by a neoplastic epithelial component associated with a dense lymphoid stroma. Rarely, MCC shows a marked lymphocytic host response or can even mimic a LEL carcinoma. We report a new case of MCC mimicking an LEL carcinoma in a 72-year-old male; the diagnosis of MCC was made on the basis of the morphology and immunohistochemical findings. We present through this case an exceptional pattern of MCC which can be misleading, and we insist on differential diagnoses.

Skin involvement is a late complication that rarely occurs in ovarian cancer patients. This event invariably carries a bad prognosis in the course of an advanced stage ovarian carcinoma which is usually of the conventional serous type. Micropapillary serous carcinoma (MPSC) was recently recognized as a distinct neoplasm that seems to be less aggressive than conventional serous ovarian carcinoma. Indeed, a few cases of stage IV MPSC have been reported. Herein, we describe an unusual case of ovarian invasive MPSC occurring in a young woman, particularly by its mode of presentation as multiple subcutaneous nodules that were subsequently diagnosed as metastatic lesions. This case demonstrates the potential of MPSC for aggressive clinical behaviour.

While it is well recognized that the combination of amoxicillin and clavulanic acid has been associated with hepatic adverse events, there are only a few reports about amoxicillin alone causing hepatic toxicity. We describe a 34-year-old woman who developed severe cholestatic hepatitis following amoxicillin treatment.

The diagnosis of Henoch-Schönlein purpura (HSP) is difficult, especially when abdominal symptoms precede cutaneous lesions. We report three cases of adult HSP revealed by gastrointestinal (GI) involvement.
