Five patients with penile melanosis are described. The lesions consisted of macular hyperpigmentation of the penile shaft and/or glans. Histologically only hyperpigmentation of the basal cell layer was observed with no melanocytic hyperplasia. Patients had follow-up for 3 to 13 years; enlargement of some lesions was observed, but the condition remained

A case of laryngeal melanosis is presented. This is followed by the analysis of the total of nine cases reported in the English literature. Patients are men in their sixth to eighth decade of life who present with hoarseness. Histopathologic findings include pigment deposits in the basal layer of the laryngeal epithelium.

Despite many studies on melanosis thyroidi, there is no consensus concerning the nature of the pigment or its pathogenesis. Here the past literature on this subject is reviewed and results are reported on a case of melanosis thyroidi that provides fresh insight into the nature of the pigment and its genesis.

Melanosis duodeni is a rare benign condition that has only recently been recognized. We describe melanosis duodeni in a 64-year-old woman who had been taking propranolol and furosemide for 5 years. The cause and clinical significance of this unusual finding remain obscure.

Neurocutaneous melanosis (NCM) is a rare phakomatosis characterized by a focal or diffuse proliferation of melanin-producing cells in both the skin and the leptomeninges. This syndrome is believed to result from an error in the morphogenesis of embryonal neuroectoderm.

Neurocutaneous melanosis (NCM) is a rare congenital disorder characterized by the presence of large or multiple congenital melanocytic nevi in association with benign or malignant proliferation of melanocytes in the leptomeninges. NCM is believed to occur as a consequence of an error in morphogenesis in neural ectoderm in the developing embryo.
