Progressive cribriform and zosteriform hyperpigmentation

Abstract

Five cases of progressive cribriform and zosteriform hyperpigmentation are described. The following criteria were fulfilled: (1) uniformly tan cribriform macular pigmentation in a zosteriform distribution; (2) a histologic pattern that consisted of a mild increase in melanin pigment in the basal cell layer and complete absence of nevus cells; (3) no history of rash, injury, or inflammation to suggest postinflammatory hyperpigmentation; (4) onset well after birth with gradual extension; and (5) lack of other associated cutaneous or internal abnormalities. This appears to be a newly described entity, although it resembles a Becker's nevus without hypertrichosis or an typical café au lait spot. We believe that such progressive cribriform and zosteriform pigmentation is not uncommon.

Progressive Cribriform and Zosteriform Hyperpigmentation: The Late-Onset Feature of Linear and Whorled Nevoid Hypermelanosis Associated with Congenital Neurological, Skeletal and Cutaneous Anomalies

“…In agreement with Quecedo et al [5], we believe that a wide spectrum of the disease exists between the diffuse congenital or perinatal forms of Kalter et al [1]and the acquired and segmental forms of Rower et al [4]. Our patient presents clear analogies with the one described by Bjorngren and Holst in 1990 [7].…”

“…In 1978, Rower et al [4]first described segmentary forms with onset during adolescence, which they called progressive cribriform and zosteriform hyperpigmentation (PCZH).…”

Progressive Cribriform and Zosteriform Hyperpigmentation

“…To the Editor Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a skin disease first described by Rower et al 1 in 1978. Since then, several cases have been published in Korea but only 3 articles in the dermatology literature in English.…”

“…Rower et al 1 reported 5 patients with pigmentary abnormalities with certain characteristics in common that constituted the diagnostic criteria for PCZH. These characteristics were uniform and cribriform brown macular hyperpigmentation with a zosteriform distribution; a his- tologic pattern consistent with a mild increase in melanin pigment in cells of the basal layer and complete absence of nevus cells; no history of rash, injury, or inflammation that could suggest postinflammatory hyperpigmentation; onset after birth with gradual increase in extension; and absence of other cutaneous or internal abnormalities.…”

“…There are several histologic patterns: nodular hidradenoma, solid-cystic hidradenoma, and clear-cell hidradenoma. 1,4,5 Correct diagnosis of hidrocystoma and hidradenoma is difficult solely on the clinical presentation and subsequent…”
