Asymptomatic Plaque on the Face—Diagnosis

Arch Dermatol. 2008;144(10):1383-1388. doi:10.1001/archderm.144.10.1383-f

Findings from histologic examination showed an essentially unremarkable epidermis; however, the upper dermis showed chronic inflammation and edema. The deep dermis contained a large area of pooled mucin with islands of basaloid epithelial cells displaying round to oval nuclei with even chromatin. The patient was referred to the head and neck surgeons for excision. He was also seen by the oncologists for a systemic workup, the findings of which were negative for extracutaneous disease. The patient underwent wide local excision, with placement of a split-thickness skin graft to repair his defect. At 4 months after surgery, the patient has experienced no recurrence of his tumor.
