Role of fine needle aspiration cytology in the diagnosis of primary malignant fibrous histiocytoma of the lung

Fine Needle Aspiration Cytology of Metastatic Scalp Nodules

“…When they do occur, they are found in the head and neck area, particularly the scalp 9,10 ; a number of cases of follicular thyroid carcinoma with scalp metastases have been reported. 5,9,11 In a series by Mondal et al, 5 follicular carcinoma of the thyroid accounted for 30% of metastatic deposits in the scalp. Scalp metastases from thyroid carcinoma result from malignant cells migrating along the external carotid artery.…”

“…The discomfort, risk and expense of extensive investigations may be avoided if attention is given to the most likely source of cutaneous metastasis. The role of FNAC in the diagnosis of malignant scalp nodules was studied by Mondal et al 5 That study, however, included both primary lesions of and lesions metastatic to the scalp as well as the underlying skull bones. Cutaneous metastasis can be limited to the scalp, as very well exemplified by our study.…”

“…2 Although a few reports are available on the scalp as a metastatic site from underlying malignancies, 2-4 the role of fine needle aspiration cytology (FNAC) in evaluating such lesions has rarely been discussed. 5 The object of the present study was to analyze cases of palpable cutaneous/subcutaneous scalp nodules and evaluate the clinical features and value of FNAC in their diagnosis.…”
