ABSTRACT
The cytomorphology of skin adnexal tumours has not been described extensively in literature. We report the first case of trichofolliculoma, a hair follicle hamartoma, which was subsequently diagnosed by excision biopsy. A 19 year old woman presented with a nodule on the dorsal aspect of the finger which was clinically suspected to be a myxoid cyst. FNA showed several cohesive as well as arborising branched groups of squamous cells with evidence of keratinisation. The background had dispersed and loosely clustered sebaceous cells. The excision biopsy revealed a trichofolliculoma. Cytology is a useful tool in the diagnosis of skin adnexal tumours. The finding of cohesive, branching keratinized squamous cell clusters admixed with sebaceous cells may suggest a diagnosis of trichofolliculoma, as was seen in the present case.

An unusual combination of two benign breast neoplasms adenomyoepithelioma and phyllodes tumor presenting as a solitary breast lump have been described. Both these tumors have tendencies to recur and have malignant potential. This patient also presented with a recurrent breast neoplasm. The case is reported for its rarity.

Lobular carcinoma is the most common pitfall in the cytodiagnosis of breast lesions. Of the cytological features described intracytoplasmic lumina are stressed by many authors as an important diagnostic feature. The present study aims at evaluating the importance of intracytoplasmic lumina in the cytodiagnosis of lobular carcinoma along with other cytological features. Fine needle aspirates from 11 cases of histologically proven classical lobular carcinomas of breast were reviewed. It was observed that the low cellularity, dispersed dyscohesive small cells, mild pleomorphism, nuclear moulding and Indian filing were the most important cytologic features which aid in the diagnosis of lobular carcinoma where as intracytoplasmic lumina were of little significance.

Intestinal neuronal dysplasia is a rare cause of bowel obstruction in neonates and infants, the diagnosis of which poses a formidable challenge to both clinicians and pathologists alike. The importance of this entity lies not only in the fact that it mimics Hirschsprung's disease, but also in that untreated cases, particularly of type A, may prove fatal. The authors describe one such case of intestinal neuronal dysplasia of type A, which was diagnosed at autopsy.
