“…HMB45 immunostaining is consistently positive in granular cells of melanocytic nevi with granular cell change, pointing to increased melanosome activity 21 . Its resemblance to granular cell fibrous papules 22 has been reported, challenging the diagnosis if the tumor arises on the face of the patient.…”

“…Granular cell FP is a rare histopathological subtype, which may mimic non‐neural dermal granular cell tumor, granular cell tumor of unknown differentiation, granular cell basal cell carcinoma, and granular cell dermatomyofibroma 12,13 . Although the dendritic cellular pattern was not evident in hematoxylin & eosin sections due to conspicuous cytoplasmic granular cell change (related to degenerative lysosomal accumulation), strong CD163 immunostaining alluded to the proliferation of dermal dendrocytes.…”
