A 62-year-old man presented with complaints of multiple dark eruptions involving his lower limbs, back, chest, and parts of the upper extremities. The lesions appeared 10 years ago on the lower limbs and progressed to involve the other parts of the body over the past 3 years. There was no history of itching, trauma, chronic scratching or friction, no systemic symptoms and no similar complaints in other family members. On examination, multiple, discrete, hyperpigmented, papules were present on the shins, [] and similar smaller papules were seen on the upper back, chest, abdomen, upper arms and few on the thigh and gluteal region [Figure and ]. Histopathological examination revealed a hyperplastic epidermis and globular masses in the dermal papillae []. Congo red staining revealed amorphous, eosinophilic deposits in the papillary dermis []. Routine laboratory investigations including complete blood count, blood sugar levels, renal, hepatic, urinary analysis, and thyroid function tests were within normal limits.\nA diagnosis of lichen amyloidosis was made on the basis of clinicopathological findings, and the patient was given topical clobetasol propionate and salicylic acid combination along with oral acitretin 25 mg/day.
