“…Shortness of the ipsilateral arm was reported by Copeman and Jones [1965], Moore and Schosser [1985], Glinick et al [1983], as well as by Glinick and Alper [1986]. Asymmetry of limbs was also noted by Lucky et al [1981] and Blanc et al [1988]. They described this as an enlargement of the ipsilateral limb but it cannot be excluded that in fact the asymmetry was caused by hypoplasia of the contralateral limb.…”

The new term Becker nevus syndrome is proposed for a phenotype characterized by the presence of a particular type of organoid epithelial nevus showing hyperpigmentation, increased hairiness and hamartomatous augmentation of smooth muscle fibers, and other developmental defects such as ipsilateral hypoplasia of breast and skeletal anomalies including scoliosis, spina bifida occulta, or ipsilateral hypoplasia of a limb. The present review includes 23 cases that can be categorized under this designation. The Becker nevus syndrome usually occurs sporadically. The associated anomalies tend to show a definite regional correspondence, suggesting a common origin from an early postzygotic mutation.

“…Becker’s naevus occurs in association with underlying developmental and structural abnormalities of bone and soft tissue [7, 8, 9, 10, 11] as well as with accessory scrotum [12] and congenital adrenal hyperplasia [13]. Various conditions may also develop within Becker’s naevus including smooth muscle hamartoma [14], connective tissue naevus [15], solitary plexiform neurofibroma [16], acneiform papules [17], perforating granulomatous folliculitis [18] and pityriasis versicolor [19].…”

We report a case of accessory mammary tissue of type 2a (or polythelia) entirely localized within a Becker’s naevus of mixed type in a 32-year-old Caucasian woman. Polythelia was congenital in origin while Becker’s naevus appeared during puberty. Renal ultrasonographic studies, laboratory examinations and other instrumental investigations were either normal or negative. Although the association of accessory mammary tissue with Becker’s naevus has previously been reported – also in the form of mammorenal and acromammorenal syndromes – this is the first case characterized by an anatomic overlap between the two anomalies. It may be the expression of a common disturbance acting early in embryogenesis in the specific developmental fields involved.

“…S ir , Becker's naevus is a common unilateral hyperpigmented hairy cutaneous hamartoma 1 . An association of Becker's naevus with other developmental anomalies, such as ipsilateral breast hypoplasia and musculoskeletal anomalies, tends to show a regional correspondence, and these conditions are assumed to be the manifestations of chromosomal mosaicism 1,2 . We describe a man with hypohidrosis colocalized with a Becker's naevus.…”

“…Becker's naevus has been known to be associated with several developmental anomalies, such as ipsilateral breast hypoplasia, supernumerary nipples, accessory scrotum, musculoskeletal anomalies and congenital adrenal hyperplasia 1–4 . However, localized hypohidrosis in Becker's naevus is an unusual phenomenon.…”

“…Mosaicism in fibroblasts derived from one sporadic Becker's naevus lesion has been documented 5 . Developmental anomalies associated with Becker's naevus may also be manifestations of chromosomal mosaicism 2 . Urbani and Betti 6 suggested that the coexistence of polymastia with Becker's naevus could originate from one common postzygotic mutation during embryonic development or from single mutations in the two different developmental fields.…”
