Malignant melanoma arising within a nevus spilus is rare. Nevus spilus is characterized by darkly pigmented macules and papules with background hyperpigmention. We report a 65-year-old woman who presented with a melanoma arising in a nevus spilus that had been present since birth.

A 53-year-old Cambodian woman presented with nodular masses on the right arm suggestive of a sarcoma-type malignancy. The masses were excised and identified as multiple benign eccrine poromas. The patient re-presented after two years with large relapsed tumours and axillary lymph node involvement. A forequarter amputation was undertaken. Histology confirmed the diagnosis of a porocarcinoma, which was likely to be due to malignant transformation of the original poromas. The size and multiplicity of the tumours represents a highly unusual presentation of these rare eccrine neoplasms.

This paper highlights the role of fine-needle aspiration cytology (FNAC) in 15 cases of metastatic soft-tissue sarcomas involving lymph nodes. Histopathology reports of the primary tumor were available in all cases. Histological diagnoses correlated well with the cytology reports. The most common type of sarcoma to involve the lymph node was embryonal rhabdomyosarcoma (6 cases), followed by synovial sarcoma (2 cases), leiomyosarcoma (2 cases), malignant fibrous histiocytoma (2 cases), fibrosarcoma (1 case), malignant peripheral nerve sheath tumor (1 case), and rhabdomyosarcoma (1 case). FNAC was thus helpful in the early diagnosis, proper staging, and management. Importantly, it obviated a lymph node biopsy in the majority of cases.

Twentyfive normal male volunteers undergoing a ten weeks course in the practice of yoga have been studied by some parameters of ventilatory functions tests. The observations recorded at the end of ten weeks of the course have shown improved ventilatory functions in the form of lowered respiratory rate, increased forced vital capacity, FEV1, maximum breathing capacity and breath holding time, while tidal volume and %FEV1, did not reveal any significant change. Thus, a combined practice of yoga seems to be beneficial on respiratory efficiency.
