“…There is no evidence of lichenoid infiltrate or basal cell layer damage and mast cells are normal in number. The other important characteristic histopathological finding "pigmented papillomatosis, " has been mentioned by many authors hence, laying emphasis that it should be included as one of the diagnostic criteria for IEMP [4,12]. The present case fulfilled the diagnostic criteria of IEMP [3] i.e.…”

“…of a 24-year-old woman lasting 21 years who was characterized by several periods of spontaneous resolution followed by recurrences [27] while the other case is of a 24-year-old man who presented with IEMP lesions of 20 years duration. The patient never had spontaneous resolution but his disease stopped progressing followed by a sudden aggravation 16 years later [12].…”

“…IEMP is a rare under-reported skin disorder which is now regarded as the clinical reminiscent of acanthosis nigricans lesions [5][6][7]. After careful review of the pertinent literature till date, less than 50 cases of IEMP have been documented worldwide with handful of them being reported from India [1,5,6,[8][9][10][11][12]. The largest series of 10 cases has been published by Jang KA et al from Korea [13].…”

Idiopathic eruptive macular pigmentation is an unfamiliar dermatological disorder which is characterized by the presence of multiple discrete asymptomatic brownish-black macules and flat plaques involving the face, neck, trunk, and proximal extremities especially in pediatric population. It is important to differentiate this uncommon entity from other pigmented dermatosis as it undergoes spontaneous resolution without any residual pigmentation or scarring and thus contraindicating any unnecessary aggressive therapeutic interventions. An experience of one such case in a 6-year-old Indian boy is being reported herewith so as to create awareness amongst the dealing physicians.

“…[910] We need to differentiate it from the conditions that produce dermal melanosis, since compared to the latter, IMEP undergoes spontaneous resolution and hence has a better prognosis, though cases manifesting persistent pigmentation have been rarely reported. [14]…”

Context:An umbrella term, acquired dermal macular hyperpigmentation (ADMH), has been proposed to denote conditions including ashy dermatosis, erythema dyschromicum perstans, lichen planus pigmentosus, and idiopathic macular eruptive pigmentation.Aims:To classify the patients manifesting ADMH on the basis of histology.Settings and Design:In this retrospective, cross-sectional study, histology specimens of patients of ADMH, who underwent skin biopsy in our institution from 1.1 2015 to 31.12.2017, were included after obtaining ethical clearance.Materials and Methods:The histology specimens of patients of ADMH were reviewed by the pathologist and classified. Clinical features of individual patient were collected from previous records and the data analyzed.Statistical Analysis Used:Pearson's Chi-square test was used to determine significance of association between age of onset and duration of pigmentation with histology type.Results:Three patterns of histology were identified in the study group (17 males and 13 females). Type 1: Basal cell degeneration and moderate to dense inflammation (12 patients, 40%), type 2: Significant pigment incontinence and sparse inflammation without basal cell degeneration, (12 patients, 40%), and type 3: sparse inflammation without basal cell degeneration or significant pigment incontinence (six patients, 20%). Statistically significant association was noted between age of onset of pigmentation and histology type (P value, 0.02).Limitations:Main limitation was the small sample size.Conclusions:Prospective studies evaluating the clinical progression and dermoscopy features and analyzing serial biopsies of ADMH patients may confirm whether the histology patterns observed represent different stages of same disease process or are different entities.

“…We laud Subhadarshini et al . [ 1 ] for publication of their interesting case of idiopathic eruptive macular pigmentation in an Indian male. As they have pointed out this case differs from others described earlier in two aspects, namely, the persistence of lesions unchanged for 16 years and an aggravation thereafter for one year and association of acanthosis nigricans in the axillae, a finding that has not been described earlier in idiopathic eruptive macular pigmentation (IEMP).…”
