A 43-year-old male presented with multiple asymptomatic papules on the back of the right side of the chest of 1 year duration. He was asymptomatic a year back then he developed small papules on the right side of the front of the chest initially and later on involved the front and back of the chest. No history was suggestive of leprosy and hyperlipidemias. Family history was negative for similar problem. Examination revealed multiple skin-colored to yellowish papules distributed on the front and back of the chest and shoulder region on the right side [Figure 1]. Also, there were multiple hyperpigmented macules on the right infrascapular region. There was no nerve thickening and no sensory deficit and there were no hypopigmented or anesthetic patches. Systemic examination did not reveal any abnormality. Routine investigations including complete blood picture, blood sugar, complete urine examination, blood urea, serum creatinine, liver function tests and serum lipid profile were normal. Fundus was normal. A slit skin smear for acid fast bacilli was negative. A punch biopsy from the representative lesion subjected to histopathological examination revealed a cyst with an intricately folded wall, lined by two to three layers of flattened squamous epithelium and the absence of the granular layer. Lobules of sebaceous glands were found embedded in cyst lining. The lumen was filled with amorphous eosinophilic material and multiple hair shafts [Figure 2] [Figure 3] [Figure 4].
