Objectives: Fine-needle aspiration cytology (FNAC) has emerged as an indispensable tool to discriminate thyroid lesions into benign or malignant for appropriate management. The need for simplicity of communication and standardization of terminology for thyroid FNAC reporting led to introduction of "The Bethesda system for reporting Thyroid Cytopathology" (TBSRTC) in a conference held at the National Cancer Institute in 2007. This study aims at establishing the reproducibility of TBSRTC for diagnosing thyroid lesions. Materials and Methods: The present study comprised thyroid FNAC from 107 patients retrospectively over a period of 1.5 year (June 2013 to December 2014), which were reviewed by two trained cytopathologists and re-categorized according to TBSRTC. The interobserver variation and reproducibility of the reporting system was statistically assessed using Cohen's kappa. Results: The cytopathologists were in agreement in 98 out of 107 cases (91.5%). Maximum concordance was noted in benign category (91 of 96 cases; 92.85%), followed by 2 cases each in nondiagnostic/unsatisfactory (ND/US) and follicular neoplasm/suspicious for follicular neoplasm (FN/SFN) category (2.04% each) and 1 case each in atypia of undetermined significance/follicular lesion of undetermined significance (AUS/FLUS), suspicious for malignancy (SUS), and malignant category (1.02% each). The highest diagnostic disagreement was noted among ND/US and benign and benign and FN/SFN categories. Conclusion: The utilization of TBSRTC for reporting thyroid cytology should be promoted in our country because it provides a homogeneous, standardized, and unanimous terminology for cytological diagnosis of thyroid lesions. The present study could substantiate the diagnostic reproducibility of this system. [ABSTRACT FROM AUTHOR]

Fibroepithelioma of Pinkus (FEP) is a rare, indolent variant of basal cell carcinoma (BCC) with a unique anastomosing type of epidermal hyperplasia. Certain benign and neoplastic conditions including BCC are known to develop in a setting of chronic lymphedema. We report for the 1st time the histological spectrum of evolution of a large exophytic multinodular FEP, bearing a single initiating focus of BCC, in preexisting chronic lymphedema of the lower limb. The lesion possibly evolved from long-standing local immune suppression, and clinically resembled a high-grade carcinoma. Oozing lymphatic fluid may interfere with the success of skin grafting following wide local excision in a lymphedematous limb, thus offering a challenging scenario from the management point of view.

Aims: Tzanck smear is an old but useful test for diagnosis of cutaneous dermatoses. The aim of this study was to highlight the potential usefulness and diagnostic pitfalls of Tzanck smear for diagnosis of cutaneous dermatoses and infections. Materials and Methods: This hospital based cross-sectional study was carried out on all Tzanck smears received for a period of twenty months (January 2014-August 2015). The smears were assessed to establish the utility of Tzanck smears in corroborating or excluding a diagnosis of immunobullous lesion or herpetic infection. Cases with discrepant diagnosis on histopathology were reviewed to identify additional cytomorphological features. Results: A total of 57 Tzanck smears were performed during the study period. Out of the 18 clinically suspected cases of immunobullous disorders, Tzanck smear findings corroborated the clinical diagnosis in 7/18 cases, one case was diagnosed as cutaneous candidiasis, and diagnosis of immunobullous lesions could be excluded in 5/18 cases. Out of the 19 suspected cases of herpetic infections, viral cytopathic effect was observed in 8/19 cases. Besides immunobullous lesions and herpetic infections, acantholytic cells were also observed in spongiotic dermatitis and genodermatosis. Dyskeratotic keratinocytes seen in vacuolar interface dermatitis were not easily distinguishable from acantholytic cells on Tzanck smear. Conclusions: Tzanck smear test is an inexpensive and useful diagnostic tool for certain skin diseases. It can aid in establishing a rapid clinical diagnosis and can serve as a useful adjunct to routine histological examination. We recommend the use of Tzanck smear as a first-line investigation for vesiculobullous, erosive, and pustular lesions. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 40-year-old female who developed worsening dyspnoea and dry cough. She undergone chest X-ray and a bilateral nonhomogenous infiltrates predominantly in mid and lower zones with bilateral effusion was revealed. The patient was diagnosed with pleural effusion as shown in the pulmonary proteinosis.

Leprosy is a chronic infectious disease caused by Mycobacterium leprae. The manifestations of this disease varies across the spectrum of tuberculoid (TT) to lepromatous (LL) leprosy.The course of this indolent disease is interrupted by acute exacerbations in the form of leprare actions. Erythema nodosum leprosum (ENL), a type 2 lepra reaction, occurs in lepromatous or borderline lepromatous cases, usually in response to multidrug therapy. Early detection and timely management of these patients is important to reduce the associated morbidity. We report two clinically unusual cases of ENL on fine-needle aspiration cytology. In one case, antileprosy treatment was completed 10 years back, whereas in the other case, ENL was the presenting feature of the disease. Cytological examination of swelling in both the cases showed neutrophils, lymphoid cells, clusters of foamy macrophages, histiocytes, and giant cells. Fite stain was positive, which confirmed the cytological diagnosis of ENL. [ABSTRACT FROM AUTHOR]

The primary and metastatic tumors of the skin can be effectively diagnosed by fine needle aspiration cytology (FNAC); however, the cytomorphological features of skin adnexal tumors are rarely described in the literature. We hereby describe the cytological features of two histologically confirmed cases of benign skin adnexal tumors. Case 1 is of a 46-year-old female who presented with an elevated firm nodule over the scalp. A cytological diagnosis of benign adnexal tumor possibly of sebaceous origin was given. The nodule was excised and histopathological examination confirmed the diagnosis of sebaceoma. Case 2 is of a 19-year-old male who presented with a pigmented scalp swelling. Cytomorphological features were suggestive of benign skin adnexal tumor with foci of melanin pigment. The swelling was excised and histopathological examination confirmed the diagnosis of eccrine poroma. To the best of our knowledge, only one previous report of sebaceoma and no report of eccrine poroma describing the cytological findings of these two tumors exist. We report these two cases of benign skin adnexal tumors to discuss the cytological features and the potential diagnostic dilemma that they pose to the cytologist. [ABSTRACT FROM AUTHOR]

The article describes the case of a 60-year-old female presented with painful vesiculo-bullous lesion over right side chest and back. Case highlights include differential diagnosis of herpes zoster and lymphedema with lymphangioma and cutaneous metastasis, major sites of metastases in breast carcinoma, and skin biopsy showing mild atrophic epidermis with intraepidermal bulla and presence of atypical cells infiltrating into dermis.
