Pigmented Epithelioid Melanocytoma in a Child: Unusual Clinical Presentation

369 intravenous adenosine is known to adversely cause facial flushing, headache, palpitations, light headedness, dizziness, blurring of vision and nausea, the local pain or discomfort and local flushing are not described. These adverse events were probably caused by intra-arterial injection of adenosine in the given case. In a clinical trial done by Costa et al [6] , adenosine injection in the ...

Case Report of a Large Pigmented Epithelioid Melanocytoma With Suspected Lymph Node Metastases

Objective: Pigmented epithelioid melanocytoma was proposed by Zembowicz et al in 2004 including lesions previously diagnosed as human animal-type melanoma and epithelioid blue nevus. Tumors are composed of epithelioid and spindled melanocytes with heavy pigmentation. Methods: We report a case of pigmented epithelioid melanocytoma in 47-year-old Asian woman. The tumor sized 10 × 6 × 2 cm on the ...

Widely infiltrating epithelioid malignant peripheral nerve sheath tumour of skull base.

The epithelioid variant of malignant peripheral nerve sheath tumours is a rare histological entity, and the occurrence of a malignant peripheral nerve sheath tumour in the skull base is even more unusual. We report a case of a 52-year-old man who presented with reduced hearing in the left ear, giddiness and left-sided facial weakness of short duration. He was a known hypertensive. On examinatio...

CORRELATION BETWEEN EXPRESSION OF CLASS I ANTIGEN AND DEVELOPMENT OF TUMOUR INFILTRATING LYMPHOCYTES (TILS) FROM TUMOUR BIOPSIES OF PATIENTS WITH BLADDER CANCER

This report presents the findings of TIL development from tumour biopsies of patients with bladder cancer. Analysis of tissue sections showed the presence of T cells in intra-epithelial layer in 8 of 12 cases investigated. In a larger group of patients, TILs were established from 7 of 20 cases and expansion of these cells in Interleukin-2 (IL-2) in the presence of conditioned medium (CM) r...
