ABSTRACT
A 40-year-old woman presented with a scalp swelling. A careful clinical examination revealed a left-sided deep-seated thyroid nodule. Fine needle aspiration from both sites disclosed a microfollicular architectural pattern on Giemsa stain and pale nuclei with nuclear grooves on Papanicolaou stain, indicating the possibility of follicular variant of papillary thyroid carcinoma with metastasis to the scalp. Histologic tissue evaluation confirmed the diagnosis. Thus, a diligent search for nuclear features should be performed to enable a diagnosis of follicular variant of papillary thyroid carcinoma on cytology. This helps in patient management obviating the need for a second surgical intervention.

Recurrent chondroblastoma with pulmonary and palatal metastasis is a rare occurrence. We report the cytological and histological findings of such a case in a 33 years old male, where the primary diagnosis of metastatic chondroblastoma was made on FNAC, which was later confirmed on histopathology. The present case highlights that, some chondroblastomas do exist, that are capable of pursuing a malignant course.

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.

A female aged 49 years presented with pain and progressive swelling of right lower abdomen. She was operated upon and gross examination revealed a proliferative growth in the fimbrial end of the right fallopian tube. Microscopically the tumour comprised of adenocarcinoma and component of spindle cell stromal sarcoma with areas of chondrosarcoma as heterologous element. A diagnosis of malignant mixed mullerian tumour of the fallopian tube, clinically FIGO stage III was made, which is extremely rare in available literature.

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.

A 16 years old female who presented with abdominal swelling and secondary amenorrhoea was subsequently diagnosed as Sertoli Leydig cell tumour of ovary revealing intermediate differentiation with heterologous element. The case is reported in view of its rarity.
