Sinus histiocytosis with massive lymphadenopathy (SHML) is a benign, self‐limiting condition of unknown etiology, which generally presents as massive bilateral cervical lymphadenopathy. It is important to distinguish SHML from other causes of histiocytosis because of the different treatment modalities. This study was carried out to assess the utility of fine‐needle aspiration cytology (FNAC) findings in SHML and to distinguish if from other reactive lymphadenopathies. The lymph nodes in 4 patients (3 male and 1 female) presenting with massive bilateral cervical lymphadenopathy were aspirated. All presented with persistent bilateral cervical lymphadenopathy, polymorphnuclear leukocytosis, and raised erythrocyte sedimentation rate (ESR). Smears showed a reactive lymphoid population consisting of mature lymphocytes, plasma cells, a few polymorphs, and many histiocytes showing emperipolesis. Based on the cytologic and clinical findings, a diagnosis of SHML was made. Histopathology confirmed the diagnosis in all cases. A conclusive diagnosis of SHML can be based on cytology, provided that the cytologic findings are interpreted in the appropriate clinical context. Biopsy can be avoided in these patients. Diagn.

Cervical melanoma is a rare neoplasm and is seldom diagnosed by cervical scrape cytology. The possibility of metastatic melanoma should be excluded before making a diagnosis of primary cervical melanoma. We present a case of primary cervical melanoma diagnosed by cervical scrape cytology and a review of literature. The patient presented with vaginal bleeding of 3 mo duration and an ulcerated cervical growth. Cervical smear showed bizarre and abnormal cells containing pigment.

Spontaneous infarction is an uncommon complication occurring in fibroadenoma of the breast. Although infarction following fine-needle aspiration has been reported in the literature, to the best of our knowledge this is the first reported case where infarction was encountered on first-time aspiration. It is necessary to distinguish infarcted fibroadenoma from mastitis, duct ectasia, mammary tuberculosis, and carcinoma on cytology smears. Lack of knowledge of this entity may lead to an erroneous diagnosis of inflammatory lesion or carcinoma. We report the first case of cytological and histological findings in spontaneous infarction of fibroadenoma in 13-yr-old female.

Background:Snake bite envenomation is a major public health concern in developing countries. Acute kidney injury (AKI) is as important cause of mortality in patients with vasculotoxic snake bite.Aims:This study was to evaluate the clinical profile of snake bite patients and to determine the predictors of developing AKI following snake bite.Materials and Methods:Two hundred and eighty-one patients with snake envenomation were included. Eighty-seven patients developed AKI (Group A) and 194 (Group B) did not. History, examination findings and investigations results were recorded and compared between the two groups.Results:In group A, 61 (70.11%) patients were male and in group B, 117 (60.30%) patients were male. Out of 281 patients, 232 had cellulitis, 113 had bleeding tendencies, 87 had oliguria, 76 had neuroparalysis, and 23 had hypotension at presentation. After multivariate analysis, bite to hospital time (P = 0.016), hypotension (P = 0.000), albuminuria (P = 0.000), bleeding time (P = 0.000), prothrombin time (P = 0.000), hemoglobin (P = 0.000) and total bilirubin (P = 0.010) were significant independent predictors of AKI.Conclusions:AKI developed in 30.96% of patients with snake bite, leading to mortality in 39.08% patients. Factors associated with AKI are bite to hospital time, hypotension, albuminuria, prolonged bleeding time, prolonged prothrombin time, low hemoglobin and a high total bilirubin.

Rhinocerebral mucormycosis is a rapidly fatal fungal disease which involves the nose, paranasal sinuses, orbit and central nervous system. The fungal infection is usually secondary to immunosuppression, diabetic acidosis, or antibiotic, steroid or cytotoxic therapy. It can also occur in patients suffering from burns, malignancy and haematological disorders. Current treatment consists of correction of the underlying disorder, repeated debridement of the wound in combination with intravenous amphotericin B.This paper describes our experience with a case of rhinocerebral mucormycosis. This is an unusual case in which mucormycosis was seen in a young female where no underlying cause was found. She responded to surgical debridement in combination with intravenous amphotericin B.

This study was carried out to examine the cytomorphologic features of metastatic breast tumors and to assess the utility of fine‐needle aspiration cytology (FNAC) in diagnosing these tumors. The study group comprised five females and one male, all presenting with a breast mass. Their ages ranged between 35 and 65 years. FNAC of the breast mass was done in all cases. Three of the cases were previously diagnosed as squamous cell carcinoma (SCC) of the cervix, mucinous cystadenocarcinoma (MCA) of the ovary, and melanoma. Three cases presented initially with a breast mass. These included melanoma, non‐Hodgkin's lymphoma (NHL), and plasmacytoma. The diagnosis of NHL was confirmed on histology. The patient with plasmacytoma presented primarily with a breast lump but subsequently developed multiple myeloma, and in one case of melanoma the primary tumor was detected after breast metastases. Preoperative FNAC of extramammary tumors metastatic to the breast is invaluable because the management of the patient differs entirely from that of a primary neoplasm. An accurate diagnosis can be made with the help of clinical and radiological correlation. If available, a perusal of previous history and biopsy material may prove useful. Diagn.

Background:Epidermoid cysts, one of the common benign intradermal or subcutaneous tumors commonly result from the trauma to the pilosebaceous unit in the hair bearing area. In areas without hair, these cysts are considered implantation and proliferation of squamous epithelium into the dermis due to injury.Aims:The aim is to evaluate the clinicopathological details with emphasis on unusual findings related to epidermoid cysts.Study Design:This is a retrospective cross-sectional study carried out over 2 years.Materials and Methods:A total of 103 cases of epidermoid cysts were included in the study. The clinical details such as age, gender, sites, and dimensions were noted. The histopathological findings were evaluated and correlated with the clinical findings.Results:The highest incidence was observed in the age group of 21–30 years (23.3%, 24/103) and the most common affected region was the head and neck region (32%, 33/103). The size of cysts ranged from 0.3 to 9 cm in diameter with a mean of 2.1 cm. The unusual sites observed in this study were four at the left sole, two at right sole, two at prepuce, and one each at the right finger, left palm, and oral cavity. Histopathological findings included rupture of epidermoid cysts with giant cell reaction, melanin pigmentation, and association with other pathologies such as keloid and lipoma.Conclusion:Epidermoid cysts are common benign intradermal or subcutaneous tumors, but they can have unusual presentations and histopathological findings. Epidermoid cysts need early diagnosis and treatment as they can cause cosmetic and functional impairment.

Vulvar cancer is an uncommon malignancy of the female genital tract in developing countries, accounting for 3% of gynaecological cancers. Here, cervical cancer is an everyday problem; ovarian cancer is the second commonest gynaecological cancer; endometrial is less common and vulvar cancer is rare. It is advanced at admission, though is a visible cancer. Records of women who had histopathologically proven vulvar cancer over 24 years were analysed for epidemiological status and preventive possibilities. During the analysis period, 9,419 total cancer cases were diagnosed; 4,726 (50.17%) were in women. A total of 39.52% (1,868 of 4,726) were gynaecological; 18 cases were vulvar (0.38% of the 4,726 women with cancer) and 0.96% of the 1,868 gynaecological cancer cases. Decreasing trends were 2.25% between 1984 and 1988, down to 0.33% between 2004 and 2008. Leading presenting complaints were: dyspareunia, 88.88% (16 of 18 patients); pruritus 13; ulcers 14; vulvar swelling 12 and urinary problems 13. Dystrophy was present in 8 of 18 cases. Overall, four had stage I, one stage II, three stage III and four stage IV disease at admission; all at labia majora or minora, some too advanced to know origin. Four women with metastasis in the lungs, liver and bones could only be given palliation. While vulvar cancer is uncommon, advanced disease at admission is a concern. Awareness is essential. Research is needed as to why cervical cancer is common and vulvar uncommon, as HPV plays a major aetiological role, so that cervical cancer can be prevented, with early diagnosis, management of vulvar cancer should also be available.
