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.

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.
