Osler-Weber-Rendu syndrome: a case report with familial clustering.

Osler-Weber-Rendu syndrome, also known as hereditary hemorrhagic telangiectasia, is a rare autosomal dominant disorder manifested by telangiectases of the skin and mucous membranes and arteriovenous malformations of various organ systems. We present a case of Osler-Weber-Rendu syndrome with 11 affected members in her family.

Blaschkoid angioma serpiginosum: A dermoscopic diagnosis

The patient we presented had no known risk factors for nasal mucosal dysplasia. However, he had used nasal steroid (mometasone furoate, beclomethasone dipropionate) sprays with benzalkonium chloride for the last 2 years. Therefore, we suggest that long‐term use of intranasal corticosteroids with benzalkonium chloride can lead to high‐grade dysplasia in the nasal mucosa. We present an unusual case of nasal mucosal dysplasia in an otherwise healthy young man to emphasize the possible side effects of benzalkonium chloride in the upper respiratory tract.

A case of neurofibromatosis type 2 (NF2) with classic imaging and skin findings

Neurofibromatosis is a neurocutaneous, tumor predisposing, inheritable disorder characterized by tumors of the brain and spine and the presence of skin lesions. The most important tumors associated with neurofibromatosis are vestibular nerve schwannomas, with others being meningiomas and ependymomas. The cord is also affected by tumors, ependymoma being the commonest, besides meningiomas and schwannomas. We present a case with café au lait macules, neurofibromas in the skin, bilateral VIII cranial nerve schwannomas, multiple meningiomas in the brain and spine, ependymomas in the brain and spine, and schwannomas in the cauda equina nerve roots.

Linear and whorled nevoid hypermelanosis with depigmentation

Linear and whorled nevoid hypermelanosis (LWNH) is a rare disorder of pigmentation characterized by hyperpigmented macules in a linear or whorled streaky configuration. Lesions are distributed mainly on the trunk and extremities, sparing the palms, soles, and mucosae. Depigmentation occurring in the pre-existing whorls has not been reported till date. Herein, we report one such rare case of familial LWNH with depigmentation.

A common but underreported entity of papulonecrotic tuberculid

Papulonecrotic tuberculid is characterized by symmetric eruption of necrotizing papules on extensor aspect of extremities, sometimes healing with a varioliform scar formation. It is infrequently reported but is not uncommon in areas where tuberculosis is endemic. Tuberculin test is generally positive while pulmonary and extrapulmonary tuberculosis is often associated. Rapid response to antitubercular therapy leaves no doubt of tuberculous etiology even when no active focus of tuberculosis is present.
