A Combination of Speckled Lentiginous Nevus with Patch‐type Blue Nevus

Abstract

A peculiar case of "nevus on nevus" was reported. A 67-year-old man had had a pigmented lesion in the left hypochondrial area since birth. The clinicopathologic findings of the pigmented lesion revealed a combination of speckled lentiginous nevus and patch-type blue nevus. This case of "nevus on nevus" is not described under the term of combined nevus as is current in the literature; it was considered to be a subtype of the type II atypical blue nevus described by Kawamura.

Agminated cellular blue naevi of the penis: dermoscopic, confocal and histopathological correlation of two cases

“…Blue naevus pattern on RCM has already been reported . There are a few cases of agminated blue naevi published in the literature describing both clinical and dermoscopic findings but RCM examination in agminated blue naevi has not been reported previously …”

A rare combination of agminated blue naevus and naevus spilus

“…We performed a mini literature review of published cases (Table ). As with our case, the NS started from birth for all the cases reviewed and the lesions were reported to change progressively over time, whereas the blue naevi were presumed to have developed in association with the NS.…”

Acquired patch‐type blue nevus with overlying vitiligo: a case report

“…10,11 The patch-type blue nevus is a bluish patch or a coalescence of macules that clinically resembles congenital dermal melanocytoses (Mongolian spot, nevus of Ito, nevus of Ota) and histologically corresponds to a common blue nevus, cellular blue nevus, or both. [3][4][5][6] The non-palpable patch-like lesion and the typical histological manifestation of common blue nevus make us believe our case is a patch-type blue nevus. Although persistent Mongolian spot (also called macular blue nevus by Hori and Takayama 6 ) can locate in extrasacral sites, the congenital onset leads us to not consider this possibility.…”

“…It is a patch-like blue lesion that histologically corresponds to a common blue nevus, cellular blue nevus, or both. [3][4][5][6] To our knowledge, a patchtype blue nevus occurring on the scalp has not been previously reported.…”
