ABSTRACT
Punctate porokeratosis is a rare variant of porokeratosis. Linear distribution of this entity has been described in very few cases. Herein, we report a case of rare coexistence of unilateral linear punctate porokeratosis and ipsilateral solitary actinic porokeratosis in an 18-year-old male
ABSTRACT
To evaluate the role of CT guided FNAC as diagnostic and supportive investigation for thoracic lesions, 190 patients were studied during two years period from March 2003 to February 2005 in our institution. A total number of 163 (85.8%) lung lesions, 22 (11.6%) mediastinal lesions and 05 (2.6%) pleural lesions were obtained; only neoplastic lesions were categorized as per WHO classification. The diagnostic sensitivity for malignancy was 97.71% and specificity 100%. Though our priority was cytological assessment, the cytological diagnosis was corroborated with clinico-radiological parameters and transbronchial biopsies whenever applicable.

The diagnostic utility of fine needle aspiration cytology as initial work up of salivary gland enlargement was assessed in one hundred and eighty-five salivary gland specimens over three years period and corroborated with histopathology, whenever feasible. All smears were evaluated according to cell size, amount of cytoplasm, cytologic atypia and presence of lymphocytes. (a) Variable cytologic appearances of pleomorphic salivary adenoma were observed. (b) Cellular pleomorphic adenoma and adenoid cystic carcinoma showed basaloid cell features. (c) Tumours with intermediate size cells and bland cytology included low grade muco-epidermoid carcinoma and cystic lesions. (d) Warthin's tumour, oncocytoma, salivary duct carcinoma and high grade muco-epidermoid carcinoma revealed large cells and abundant cytoplasm with or without atypia. A major diagnostic categories were inflammatory lesions (n = 7 5), cystic lesions (n = 9), benign tumours (n = 81), malignant neoplasms (n = 1 8) and normal acinar pattern (n = 2). Malignant tumours included muco-epidermoid carcinoma (n = 5), adenoid cystic carcinoma (n = 3), acinic cell carcinoma (n = 2), adenocarcinoma (n= 2), squamous cell carcinoma (n = 1), undifferentiated carcinoma (n= 4) and malignant lymphoma (n = 1). Histopathological correlation was possible in 40% of benign and 80% of malignant neoplasms. The overall sensitivity, specificity and diagnostic accuracy were very high. So it can be concluded that fine needle aspiration cytology can play important role in early diagnosis and subsequent therapeutic planning of salivary gland lesions.
