The presence of thin erythematous plaques on the face and patches on the extremities, more pronounced folliculotropism compared to epidermotropism, and highly expressed follicular mucinosis on histopathology, along with low Ki-67 expression and the absence of CD20 and CD68 on immunohistochemistry, contributed to classifying the disease as an indolent form of F-MF. The gene discussed is CD68; the disease is alopecia mucinosa.
