Esophageal Perforation and Pneumomediastinum Due to Delayed Diagnosis of Esophageal Lichen Planus.

Esophageal involvement of lichen planus is an under-reported and under-diagnosed manifestation that should prompt immediate treatment given its high rate of complications. We highlight a rare case of a 62-year-old Caucasian woman with history of known oral lichen planus and esophageal strictures presumed to be secondary to gastroesophageal reflux disease, that presented with esophageal food impaction resulting in perforation and subsequent pneumomediastinum after esophagogastroduodenoscopy (EGD). Further workup, including a repeat EGD, revealed that the esophageal strictures were rather a complication of lichen planus.

Blue Nevus-Like Metastasis of a Cutaneous Melanoma Identified by Fluorescence In Situ Hybridization.

A blue nevus-like melanoma is a rare melanoma variant arising from or histologically similar to a blue nevus. It can be challenging to distinguish a cellular blue nevus from a blue nevus-like melanoma, particularly in cases of blue nevus-like melanoma lacking a transition from a clearly benign component. We present a case of a 78-year-old man who refused treatment for a previously existing melanoma and subsequently developed a gray nodule near the site of the previous melanoma.

Bullous Skin Lesions in a Patient with End-Stage Renal Disease and Hepatitis C.

Bullous lesions in patients with end-stage renal disease are uncommon and can pose diagnostic and therapeutic challenges. We present a female patient with end-stage renal disease, bullous skin lesions affecting mainly sun-exposed areas, and high ferritin levels. She also had hepatitis C.
