Nevus Comedonicus: Case Report

Abstract

Nevus comedonicus is a rare cutaneous anomaly, characterized by the clustering of papules with firm, blackened horny buffers. It in general has a zosteriform pattern and affects both genders equally. In some patients, there is formation of cysts, abscesses, and fistulas, aggravating its psychosocial impact. The association with extracutaneous lesions characterizes the nevus comedonicus syndrome. Despite several therapeutic options, the result is unsatisfactory in most cases. We report the case of a man with an exuberant congenital lesion, affecting the left suprascapular region, arm, and forearm.

Marked therapeutic effect of topical adapalene on the early stage of nevus comedonicus

“…It is clinically characterized by a linear arrangement of dilated follicular openings filled with dark keratinous material and sometimes arising on Blaschko lines, probably related to genetic mosaicism. [1][2][3] Several treatments have been reported in NC, most of them resulting in recurrences. We describe here a case of the marked therapeutic effect of topical adapalene on the early stage of NC.…”

Chronic cough in a child: a novel therapeutic approach

“…2 It can be accompanied by extracutaneous symptoms and integrate a neurocutaneous disorder, with ocular, skeletal and central nervous system manifestations, known as nevus comedonicus syndrome (NCS). 1,3 Two subtypes of NC have been described: one non-pyogenic and another associated with cysts and pustules. 1 Usually, NC has a clinical diagnosis.…”

“…Pushing 50 cc of air through the tube using a syringe while auscultating the stomach with a stethoscope is a commonly described manoeuvre to determine the location of the tube, but it is of questionable efficacy. 3,4 Misplaced NG tubes placed in the left mainstem bronchus and small bowel can sound similar to adequately placed NG tubes. Taking a plain X-ray which includes both airways and the upper gastro-intestinal tract is therefore the best way to confirm the location of the tube.…”

“…Pushing 50 cc of air through the tube using a large syringe while auscultating the stomach with a stethoscope is a commonly described manoeuvre to determine the location of the tube, but it is of questionable efficacy. 3,4 Misplaced NG tubes placed in the left mainstem bronchus and small bowel can sound similar to adequately placed NG tubes. Taking a plain X-ray which includes both airways and the upper gastro-intestinal tract is therefore the best way to confirm the location of the tube.…”
