A Case of Subepidermal Calcified Nodule in Auricle / 대한이비인후과학회지

Subepidermal calcified nodule, also called as cutaneous calculi, is a rare form of calcinosis cutis, which is not associated with biochemical abnormalities, or other dermatologic disorder or systemic illness. It occurs on the face and ear of children, and is asymptomatic. It usually presents as a solitary verrucous nodule and histologically shows as basophilic granules and masses in the dermis. We experienced one case of subepidermal calcified nodule in a 9-year-old boy with auricular mass. He did not have any other dermatologic disorder or systemic illnesses. Physical examination showed a 1.5 x 3 cm sized, non-tender, hard, fixed mass on left helix. It was surgically excised. It was finally reported as calcinosis cutis. We report it with a review of the current literature.

Xanthoma Disseminatum, a Case with Laryngeal Involvement / 대한이비인후과학회지

Xanthoma disseminatum is a rare benign, normolipemic mucocutaneous xanthomatosis resulting due to the proliferation of non-Langerhans cell histiocytes. Xanthoma disseminatum typically involves the skin, particularly the flexor skin folds. Mucocutaneous involvement develops in 40-60% of patients, most commonly affecting the oropharynx, larynx, or corneae and conjunctivae. Xanthoma disseminatum may also manifest in the central nervous system. While the natural history of xanthoma disseminatum is usually benign, lesions in critical anatomical locations may result in morbidity and mortality. Curative therapy is lacking. We report a case with laryngeal involvement in a female patient. In this patient, xanthomas involved oropharynx and larynx mucosa. Dyspnea occurred due to epiglottis lesion. Tracheotomy was performed, and maintenance of breathing and decanulation were possible after epiglottectomy.
