Reticulate pigmentary disorders are rare in India. Only 15 cases of reticulate acropigmentation of Kitamura (RAPK) and 9 cases of Dowling-Degos disease (DDD) have been reported previously. To the best of our knowledge, there has been no earlier report of acropigmentation of Dohi. We herein describe 10 patients with various reticulate pigmentary abnormalities: 6 with RAPK, 2 with DDD, 1 with RAPK-DDD overlap, and 1 with acropigmentation of Dohi. Palmar pits and/or breaks in epidermal ridge pattern were absent in 2 of 6 patients with RAPK. A 23-year-old male patient had RAPK-DDD overlap. Periorbital pigmentation and pigmentation over the mucosal surface of the prepuce and corona of the glans penis were some unique features observed in this patient. His sister and mother had RAPK and DDD, respectively. We concluded that RAPK and DDD are varying manifestations of a single entity. Their presence in other family members probably depends on the degree of penetrance.
网状色素沉着性疾病在印度较为罕见。此前仅报道过15例北村网状肢端色素沉着症（RAPK）和9例Dowling-Degos病（DDD）。据我们所知，此前尚无关于土肥肢端色素沉着症的报道。我们在此描述10例患有各种网状色素沉着异常的患者：6例RAPK、2例DDD、1例RAPK-DDD重叠型以及1例土肥肢端色素沉着症。6例RAPK患者中有2例无掌部凹点和/或表皮嵴纹中断。一名23岁男性患者患有RAPK-DDD重叠型。该患者观察到一些独特特征，如眶周色素沉着以及阴茎头包皮和冠状沟黏膜表面色素沉着。他的姐姐和母亲分别患有RAPK和DDD。我们得出结论，RAPK和DDD是单一疾病的不同表现形式。它们在其他家庭成员中的出现可能取决于外显率的程度。
