A case of piloleiomyoma
Abstract:A 53 years old female patient was presented here, who had been suffering from a large number of red papules and nodules in his left upper limb extensor side for 18 years. The histopathologic assessment revealed that mild epidermis thickening, the epidermal projections extend irregularly downward, the melanin in basal layer increased, spindle-shaped tumor cells infiltrated in the superficial and middle layer of dermis without clear realm. Masson trichrome staining: tumor cells were dyed red, mixed with a small amount of collagen fibers stained with blue, α-SMA staining was positive, KP-1 staining was negative. Diagnosis: piloleiomyoma. The patient had no obvious symptoms, so only follow-up was given without any treatment.
Keywords:Piloleiomyoma  skin
