Sir, The association of a speckled lentiginous naevus, an organoid naevus with sebaceous differentiation and skeletal and neurological anomalies, constitutes a specific syndrome that has been called phacomatosis pigmentokeratotica (1). It has been hypothesized that the co-occurrence of the two different naevi reflects a so-called twin spot phenomenon (1 – 3). We herein describe an additional ca...

Sir, Naevus comedonicus was first described by Kofmann in 1895 (1). It was arranged in groups or linear patterns along Blaschko’s line and located on the face, neck, upper arms, chest and abdomen. It has been well documented that naevus comedonicus occurs as a single entity but occasionally in association with other disorders. The objective of this study was to analyse the clinical and immunohi...

Becker's naevus is an acquired persistent asymmetrical area of skin pigmentation, sometimes showing evidence of increased androgen sensitivity, and colocalizing with other developmental anomalies. We report a 30-year-old woman with clinical findings compatible with Becker's naevus on her right breast accompanied with hypoplasia of ipsilateral breast.

Sir, We describe here the case of a man aged 65-years at our first examination with non-epidermolytic epidermal naevus of a soft, papillomatous type covering large areas of the left side of his body and scalp. He reported bilateral hearing loss and earlier frequent mastoiditis. He was of short stature and had had dyspnoea since childhood affecting his sporting activities, reduced touch sensatio...

The genus Naevus Knight, 1970 is recorded from the mountains of southwestern Saudi Arabia, the first record from the Arabian Peninsula. A new species, Naevus hathali El-Sonbati & Wilson sp. n. is described here, which appears to have an asymmetric aedeagus. An illustrated key to Naevus species is presented to facilitate identification.

Meyerson phenomenon (MP) is an inflammatory, some­ times itchy, eczematous eruption usually encircling a pre-existing melanocytic naevus. The terms halo derma-titis and Meyerson's naevus are also frequently used to describe it (1). MP usually appears in otherwise healthy young male individuals, but has also been reported in females and young children (2). Apart from slight itching, no other sym...

Naevus of Ota (naevus fusculocoeruleus ophthalmomaxillaris) was described by the Japanese dermatologist, Ota, in 1939 as a dermal melanocytic hamartoma that presents as bluish hyperpigmentation along the ophthalmic, maxillary, and mandibular branches of the trigeminal nerve. It is bilateral in less than 5% cases, occurring frequently in Orientals (0.2%–1%) and darker races and rarely in white p...

BACKGROUND Heritability of naevi counts is widely acknowledged as a potential surveillance parameter for prevention purposes. The contribution of heritability to the changes seen in naevus number and morphology over time and their corresponding dermoscopic characteristics is unknown, but is important to understand in order to account for adequate prevention measures. OBJECTIVES To identify na...
