RESUMEN
Eosinophilic ulcer of the oral mucosa is a benign, reactive, self-limited lesion. Its pathogenesis is unclear, and it clinically manifests as a punched-out ulcer with surrounding indurated border, raising suspicion for a possible malignancy. On histology, an acute and chronic dense inflammatory infiltrate can be appreciated, which can extend to the deep underlying tissue (including skeletal muscle). Eosinophils are especially conspicuous on hematoxylin and eosin staining and might play an important role in the development of the ulcer. Removal of possible triggers followed by monitoring and possible biopsy are among the initial recommendations. Most lesions heal spontaneously without the need for intervention. This review aims at assisting dermatologists to easily recognize this entity, avoiding unnecessary interventions and apprehension.

Hearing loss is a prominent feature in multiple genodermatoses. Underappreciation of auditory deficits can misdirect proper diagnosis by the treating dermatologist. This review reviews the anatomic, developmental, and embryologic aspects that characterize the ear and summarizes genodermatoses that have aberrant auditory findings. The latter are classified into neural crest, metabolic, pigmentary, craniofacial, and a miscellaneous category of disorders lacking specific cutaneous findings. The algorithms provided in this review enable treating dermatologists to better recognize and manage genodermatoses with ear involvement.
