Extragonadal malignant teratoma of the foot.

This report documents the occurrence of an extragonadal malignant teratoma on the sole of the foot, in a young male. The patient also developed a groin nodule showing the same histology. The testes, retroperitoneum and mediastinum, which are usual sites of germ cell tumours were all normal, and no other primary could be detected. A teratoma growing in the tip of an extremity is a unique occurrence, biologically difficult to explain, and, which to the best of our knowledge has never been reported in literature.

Differences in oestrogen receptor status and histological grade of breast cancer in different religious communities in Bombay.

The various religious communities in India viz.Hindu, Muslim, Christian, Parsi have different breast cancer incidence rate. It is not known whether there might also exist differences in biological properties of breast cancer between these communities. To investigate this possibility we have studied the distribution of oestrogen receptor (ER) status and histological grade of tumour in these four communities. Significant differences were observed in the overall distribution of ER positivity and histological grade between the communities P less than for both parameters). Christians had the highest incidence of ER +ve (65.2%) and grade I + II tumours (16.0%), while Muslims had the lowest incidence of ER +ve (35.8%) and Grade I + II tumours (4.7%). In general, we found a significant positive relationship between ER status and age of the patient (p less than 0.0.1). The mean age of the christians was slightly but significantly higher than that of the Hindus and Muslim. The difference ER positivity between the communities might, therefore, be partly (but probably not wholly) explained by difference in age of the patients. However, the difference with respect to grade of tumour cannot be explained as a function of age since no significant association was found between grade of the tumour and age of the patient. Further investigation with respect to difference in the biology of the breast cancer between the communities are warranted.

Intractable diarrhea and melena in an AIDS patient.

A young Arab male, clinically suspected to have ulcerative colitis, was operated upon for fulminant intractable diarrhea with melena. The colon showed severe necrotizing and hemorrhagic colitis which was attributed to an opportunistic infection, viz cytomegalovirus infection. The patient's immunocompromised state was a consequence of AIDS, proved by ELISA and Western Blot test. He subsequently developed multiple brain abscesses and succumbed to uncontrolled infection.

S-100 protein in clear cell sarcomas of the tendon sheath.

Fourteen histologically proved specimens of clear cell sarcomas (CCS) of tendon sheaths were studied for the presence of S-100 protein. Eleven cases were strongly positive, and 2 cases were weakly positive. There was only one case which was absolutely negative for this protein. This technique was useful to diagnose tumours which were not only easily diagnosed as CCS or soft tissue melanomas, but also in the atypical and spindle cell variants of CCS which have to be weeded out of the large family of other morphologically allied soft tissue tumours.

Clear cell sarcomas of the tendon sheath. An experience of 22 cases seen over 16 years.

Twenty-two histologically confirmed cases of Clear Cell Sarcomas (C.C.S.) seen over a sixteen year period, are retrospectively analysed from a clinico-pathological view-point. The tumours occurred in young adults, average 36 years. Males predominated, and the lower extremity particularly the thigh and foot were the most commonly involved. Grossly, a connection with aponeurosis and tendon sheath has not been recorded consistently. Microscopically the tumour was distinctive, with their short fascicles and nests of polygonal to fusiform cells. The "clear" cytoplasm stressed in it's very name was not the rule. Melanin was demonstrated in 7 of the 22 cases, i.e. 32%, and these patients did not behave any differently from those where pigment was not seen. Immunocytochemistry for S-100 protein was done in 14 cases and was positive in 13 cases. Follow-up information revealed that 11 patients were dead of advanced disease in an average period of 24 months. Two patients were alive with disease for an average period of 3 years 7 months. Only 4 patients had no evidence of disease for periods ranging from 6 months to 26 months. Metastasis to nodes was a very frequent event, but lung and bony metastasis has also been documented.

Treatment of Askin Rosai tumor--need for a more aggressive approach.

Fifteen cases of histologically proven Askin Rosai tumor were treated at Tata Memorial Hospital over a period of 3 years. Patients included 12 men and three women. Clinical features included chest wall mass (14), pain (11), bony involvement (6), fever (4), dyspnoea (4), weight loss (1), cough (1), and hemoptysis (1). Previously treated patients received different treatment protocols, which made evaluation difficult. Of our ten patients who have completed induction therapy, five received vincristine and cyclophosphamide, whereas the other five received more aggressive chemotherapy. Complete remission has been achieved in two and four of these patients, respectively. One patient in each group had recurrence of the disease, in both cases at the local site. Thus, from our preliminary data, we suggest that Askin Rosai tumor should be treated with complete surgical excision followed by an aggressive combination of chemotherapy and local radiotherapy.

Metastatic ovarian neuroblastoma: a case report.

Ovarian metastasis of childhood tumors is rare despite their aggressive nature. The childhood tumor that spreads to the ovary most frequently is the neuroblastoma. The clinical features and frequent bilaterality of ovarian metastatic tumors are helpful diagnostic features in many cases, but when the ovarian tumor is the presenting manifestation of the disease, differentiation from various primary ovarian tumors may be difficult. In this paper, a rare case of metastatic ovarian neuroblastoma is reported.

Solid and papillary epithelial neoplasm of the pancreas. Diagnosis by fine needle aspiration cytology in four cases.

The cytologic features of four cases of solid and papillary epithelial neoplasm of the pancreas that were diagnosed on fine needle aspiration cytology are described. Papillary structures with delicate vascular cores covered with several layers of bland tumor cells were a distinctive feature. The papillae in two of the cases showed mucoid material in their cores. The cytologic features of solid and papillary epithelial neoplasm of the pancreas are distinct from those of other cystic pancreatic tumors.
