BackgroundGranulomatous prostatitis is an uncommon entity that is diagnosed incidentally on histopathology and is broadly classified as nonspecific, specific, postsurgical (post-transurethral resection), or secondary to other rare systemic granulomatous diseases. Only very few studies are available in the literature that describe the clinical and histomorphological spectrum of the disease.MethodsA retrospective analysis of histopathological records of 1,181 prostatic specimens received in the pathology department was done over a period of 13 years (January 2003 to January 2016). All histologically proven cases of granulomatous prostatitis were retrieved, and relevant clinical data were collected from patients’ records. Epstein and Hutchins classification was used to categorize these cases.ResultsTwenty-two cases of granulomatous prostatitis were identified, accounting for an incidence of 1.86%. Among these, nonspecific granulomatous prostatitis (n = 10) was the most common followed by tubercular prostatitis (n = 5), posttransurethral resection of the prostate (n = 3), allergic (n = 2), and xanthogranulomatous prostatitis (n = 2). The age range of these patients was between 41 and 75 years, with the majority of patients in their 7th decade. Serum prostate-specific antigen levels ranged between 0.88 ng/mL and 19.22 ng/mL. Hard and fixed nodules were observed on digital rectal examination in 14 cases. Transrectal ultrasound revealed hypoechoic shadows in five cases.ConclusionDespite present-day advances in imaging modalities and serological investigations, it is virtually impossible to identify granulomatous prostatitis clinically. Histopathology remains the gold standard in diagnosing the disease. However, assigning an etiologic cause to the wide spectrum of granulomas in granulomatous prostatitis requires a pathologist’s expertise and proper clinical correlation for appropriate patient management.

Background. Diagnosing adnexal tumours of the skin is a challenge due to their wide variety, infrequent occurrence in practice, and confusing morphological picture. Aims and Objectives. The present study aims to observe the spectrum of adnexal tumours at our institute and to evaluate them based on histomorphological, histochemical, and immunohistochemical methods either alone or in combination for proper identification and classification. Materials and Methods. A partly retrospective and partly prospective study was conducted on adnexal skin tumours over a period of 6 years. Relevant clinical profile was recorded. Histopathological examination was carried out and special stains were applied as and when required. Immunohistochemistry was performed where diagnosis with routine stains was not possible. Results. A total of 150 skin tumour biopsies were received. There were 87 keratotic tumours, 39 adnexal tumours, and 24 melanocytic tumours. Amongst the adnexal tumours, 51.3% eccrine, 30.8% follicular, and 17.9% sebaceous tumours were seen. In five cases, histological diagnosis was troublesome where immunohistochemistry helped in making final diagnosis. Limitations. The sample size is small. Conclusion. Histomorphology is confirmatory in majority of the adnexal tumours but few rare lesions that mimic internal malignancy require a panel of immunomarkers to rule out other possible differentials.

Dermatofibrosarcoma protuberans is a rare soft tissue sarcoma that arises from the dermis and invades deeper tissues. Usually, it behaves as an intermediate grade malignancy but in rare instances, it can metastasize. Frequent occurrences have been observed in trunk and extremities but involvement of the breast has rarely been reported. Therefore, dermatofibrosarcoma protuberans (DFSP) breast often masquerades primary breast malignancy on clinical and radiological grounds. Histomorphology and immunohistochemistry are helpful in making a definitive diagnosis. In the present case, monomorphic spindle cells were seen arranged in classical storiform pattern with large areas of myxoid change. Many times, such myxoid areas pose a diagnostic challenge and necessitate differentiation from other myxoid neoplasms. Herein, immunohistochemistry offers an advantage where tumor cells show strong reactivity for CD34 antibody. Wide surgical excision remains the treatment of choice. The salient clinical features, histogenesis, histomorphology, and immunohistochemical findings have been described with strong emphasis on the diagnostic and therapeutic management of this rare entity.
