Confluent and reticulated papillomatosis (CARP) is a rare disorder mostly seen in young adults. It is characterized by persistent dull-brown, centrally confluent, peripherally reticulate macules and papules, which coalesce to form patches and plaques on the upper trunk and neck. It is commonly confused with pityriasis versicolor and acanthosis nigricans (AN). We report the case of a 15-year-old male with multiple pigmented confluent and reticulated patches and plaques on the neck, trunk, and chin for 3 years, which was successfully treated with oral minocycline, resulting in complete resolution of lesions within 2 weeks. The morphology of CARP resembles that of various other dermatological conditions such as AN and pityriasis versicolor, and, as a result, it is frequently misdiagnosed and mistreated, leading to social embarrassment for the patient. Therefore, it is prudent for dermatologists to carry out comprehensive clinical and histopathological assessments to facilitate prompt diagnosis and management of this condition.
融合性网状乳头瘤病（CARP）是一种罕见的疾病，多见于年轻人。其特征为持续存在的暗褐色、中央融合、周边呈网状的斑疹和丘疹，这些斑疹和丘疹融合后在上胸部和颈部形成斑块。它常与花斑癣和黑棘皮病（AN）相混淆。我们报告一例15岁男性，其颈部、躯干和下巴出现多个色素沉着的融合性网状斑块3年，口服米诺环素成功治愈，皮损在2周内完全消退。CARP的形态与其他各种皮肤病如AN和花斑癣相似，因此常被误诊和误治，给患者带来社交尴尬。因此，皮肤科医生谨慎地进行全面的临床和组织病理学评估，以促进对该病的及时诊断和管理是很有必要的。
