“…In these groups of malformation, one component can predominate over the other [10]. A predominant mesenchymal stroma was observed in fibro-folliculoma (FF), trichodiscoma (TD), and trichogenic myxoma (TM) [10]. The mesenchymal components that are reported in these hamartomatous lesions include fibroblastic or fibrous with mucinous components in TD and FF or a pure mucinous stroma in TM [10].…”

However, an equal proportion of epithelial and stromal structures has been demonstrated in tricho-folliculoma (TF), fibrous papule of skin (FP), neuro-follicular hamartoma (NFH), and FSCH [10]. Other kinds of hamartoma are composed of either well-developed terminal or vellus hair follicles in TF and FP or disturbed pilo-sebaceous units in TF, NFH and FSCH, intermixed with collagenous, fibroblastic, or sclerotic stroma [10].…”

Folliculosebaceous cystic hamartoma (FSCH) is a distinct type of cutaneous hamartoma of pilosebaceous origin that usually occurs on the face. For FSCH, other parts have been reported such as the genital area, and the trunk. A 50-year-old woman presented with an asymptomatic dome-shaped scalp nodule. The clinical diagnosis was pilar cyst or tumor. Histopathological assessment showed FSCH with absolute neural component as the only mesenchymal stroma, leading to the diagnosis of folliculosebaceous cystic neural hamartoma. To the best of our knowledge, absolute neural stroma in FSCH has not been reported previously in the literature.
