Adenocarcinoma of the anal canal: A report of two cases with review of literature.

Adenocarcinoma of the anal canal accounts for about 20% of all anal canal cancers. It is subclassified into two types. (1) Colorectal type, which arises from the mucosa above dentate line and (2) extramucosal type, which includes adenocarcinoma arising in anorectal fistulae and adenocarcinoma arising from anal glands. Anal gland adenocarcinomas are extremely rare. In this article, we present two cases of anal adenocarcinoma, one colorectal type, and other anal gland carcinoma along with review of literature.

Skin Tumours – Histopathological Review of 125 Cases.

The skin is the largest organ in the body. A wide variety of hyperplastic growths and tumours, both benign and malignant are encountered in the clinical practice. Any lesion, for which the diagnosis is uncertain, based on the history and clinical examination should be biopsied for histopathological examination to rule out malignancy. Objective: To analyze retrospectively tumours of skin with respect to age, sex, clinical features and histopathological features in a tertiary referral centre in Maharashtra, India. Material & Methods: The present study consisted of analysis of tumours of skin received in the histopathology section of department of pathology over a period of 5 years that is from August 2005 to July 2010. The material comprised of biopsies and excision specimens. The clinical and histopathological details were noted. The findings were compared with those reported by other authors. Results: One twenty five (125) tumours of skin were observed. The benign tumours were slightly more common (51.2%) than malignant tumours (48.8%). The maximum number of tumours was found in 7th decade (25.6%). Maximum number of tumours were found in third decade in benign tumours (20.3%) and seventh decade in malignant tumours (37.7%). Both benign and malignant tumours of skin were common in males than females. The equal numbers of skin tumours were seen in both the head and neck region (44.8%) and the extremities (44.8%). Face was the commonest site for skin tumours (35.2%). The keratinocytic tumours, both benign and malignant were common tumours of skin (62.4%) while neural tumours were rarely observed (1.6%). The Squamous Cell Carcinoma (SCC) was the commonest malignant tumour (45.9%) followed by Basal Cell Carcinoma (BCC) (34.4%). Verrucas (32.8%) were the commonest benign tumours followed by pyogenic granuloma (21.9%). Conclusion: SCC is the most common malignant skin tumour in India, unlike the Western countries. Histopathological study is a very important step in the diagnosis of skin tumours.

Tumourlike Lesions of Skin - A Clinicopathological Analysis of 175 Cases.

As the skin is the largest and complex organ, a wide variety of tumourlike lesions are encountered in the clinical practice. The ability to properly diagnose & treat these common lesions & to distinguish them from malignant tumours is the vital skills for all clinicians. Objective: To analyse retrospectively tumourlike lesions of skin with respect to age, sex, clinical features and histopathological features in a tertiary referral centre in Maharashtra, India. Methods : The present study consisted of analysis of tumourlike lesions of skin received in the histopathology section of department of pathology over a period of 5 years that is from August 2005 to July 2010 .The material comprised of biopsies and excision specimens. The clinical and histopathological details were noted. The findings were compared with those reported by other authors. Results : One hundred and seventy five (175) cases of tumourlike lesions of skin were seen .These lesions presented as skin swellings or tumours. Maximum cases (34.8%) of tumourlike lesions occurred in fourth & fifth decades with male preponderance (1.35:1). The maximum number of cases was encountered in the head & neck region (63.4%). Their size ranged from 0.4 to 9 cms. Epidermal cyst was the commonest tumourlike lesion (59.4%) followed by dermoid cyst (13.1%).Other lesions were trichilemmal cyst, fibroepithelial polyp, keloid, hypertrophic scar and epidermal nevus. Conclusion : Tumourlike lesions are clinically diagnosed by their presentation. However, the histopathological examination confirms the clinical diagnosis. The pathologic evaluation of all tumourlike lesions is mandatory to avoid patient’s and family’s anxiety.

Hepatic angiosarcoma arising in an adult mesenchymal hamartoma.

Embryonal (undifferentiated) sarcomas arising in mesenchymal hamartoma are on record but cases of hepatic angiosarcoma (AS) arising in mesenchymal hamartoma (MH) of the liver are extremely rare. We report one such case in a 20-year-old male patient. He presented with a lump in the right hypochondriac region and pain of two years duration with rapid increase in size since two months. Ultrasonography (USG) revealed a well circumscribed mass on the undersurface of the right lobe of liver suggestive of hemangioma. The patient underwent resection of the mass. Histopathology revealed AS with areas of MH.

An unusual presentation of parathyroid adenoma--a case report.

A case of intrathyroid parathyroid adenoma which clinically and cytologically mimicked thyroid tumor is presented. The patient was normocalcemic inspite of clinical and radiological features suggestive of hyperparathyroid bone disease. The adenoma showed an area of infarction presumably accounting for the normocalcemic primary hyperparathyroidism. The case is reported for its unusual presentation.
