Erythrosis Pigmentosa Peribuccalis in an Adolescent: Dermoscopic Description and Management

Erythrosis pigmentosa peribuccalis is an infrequent condition, with fewer than 35 cases reported in the literature, that affects mainly women. It presents as small papules that form a hyperpigmented plaque around the mouth and nose. Little is known about the etiology of this condition, its dermoscopic characteristics have not been described, and no effective treatment has been reported. We report a 15‐year‐old girl with this rare dermatosis who was successfully managed with daily calcipotriol, weekly topical ivermectin, and strict photoprotection. We also describe for the first time the dermoscopic findings of this entity.

Dermoscopy of inflammatory breast cancer.

Inflammatory breast cancer is an aggressive and infiltrative malignancy that is often misdiagnosed as an infection because of its symptoms and signs of inflammation, delaying proper diagnosis and treatment. We report a case of inflammatory breast cancer showing correlation between dermoscopic and histopathological diagnoses. We highlight the utility of dermoscopy for skin biopsy site selection.Inflammatory breast cancer is an aggressive and infiltrative malignancy that is often misdiagnosed as an infection because of its symptoms and signs of inflammation, delaying proper diagnosis and treatment.
