Solitary Nodule on the Thigh

DOI: 10.4103/0019‐5154.198054 A 65‐year‐old apparently healthy male presented with an asymptomatic growth over the right thigh, present for the past 1 year. Initially, the lesion was a pea‐sized growth which gradually increased in its dimension and morphology to attain the the present size. (2.5 cm × 3 cm). Cutaneous examination showed a solitary moist firm slightly tender nodule over the lateral aspect of the right thigh. The mass had an eroded surface, fixed to the underlying structures, and bled on touch [Figure 1]. Regional lymphadenopathy was notably absent. The mass was excised in toto and histology showed a well‐circumscribed epithelial neoplasm, connected to the epidermis at multiple points. The neoplasm was composed of monomorphous cells, with several of them showing abundant pale or clear cytoplasm. Besides, there were features of ductal differentiation, cystic changes, and necrosis [Figures 2 and 3]. The stroma was characterized by thickening and hyalinization of collagen.
