Agminated lentigines may be defind as a circumscribed grouping of small pigmented macules arranged in a small or large group, often in a segmental pattern, each macule consisting of a lentiginous epidermal proliferation of melanocytes. We report five cases of agminated lentigines in otherwise healthy persons. Histologic exarnination of the pigmented lesion revealed findings consistent with lentigo simplex.

Herein we report a case of lentigo maligna that evolved into lentigo maligna melanoma. Fifteen years ago, the patient developed a pigmented lesion on the right cheek. The lesion progressed slowly, and 2 months ago, a black nodular lesion was developed in the periphery of the pigmented lesion. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanorna. She had been performed wide excision and cheek flap for reconstruction.

Partial unilateral lentiginosis is a rare pigmentary disorder characterized by the numerous unilateral lentigines on the otherwise normal skin. A 13-year-old woman presented with asymptomatic multiple brownish macules on the left periorbital area. Her mother and maternal grandfather had the same clinical features on the left abdomen. Histologic examination of the pigmented lesion revealed findings consistent with lentigo simplex. We report an interesting case of partial unilateral lentiginosis with familial occurrence.

Partial unilateral lentiginosis (PUL) is an unusual pigmentary disorder that's characterized by multiple lentigines in a unilateral distribution. The lesions often have a segmental pattern with a sharp demarcation at the midline. This is sometimes combined with other disorders such as neurofibromatosis or cafe-au-lait macules (CALMs). The presence of multiple CALMs in the same distribution as the lentigines on a PUL patient makes it difficult to differentiate PUL from segmental neurofibromatosis. We present here a 25-year-old woman with an unusual combination of several caf?-au-lait macules and scattered numerous lentigines involving the left side of the abdomen, flank and back.

Speckled lentiginous nevus is circumscribed patch of hyperpigmentation with smaller, darker pigmented macules or papules within the patch. The background shows histologic features of lentigo simplex. The speckled areas show junctional or compound nevus. Association of speckled lentiginous nevus with multiple spitz nevi was rarely reported. We report a case of multiple spitz nevi arising in a giant speckled lentiginous nevus.

Partial Unilateral Lentiginosis (PUL) is a rare pigmentary disorder characterized by the numerous lentigines confined to a body segment, with a sharp demarcation at the midline. We report two cases of PUL. A 38-year-old woman had asymptomatic discrete small hyperpigmented macules that were scattered on the T7~L1 dermatomes on the left side of her trunk and were clearly demarcated in the midline on both anterior and posterior sides. In the other case, an 18- year-old woman had hyperpigmented macules that were scattered on the left neck, shoulder, and anterior chest. Other anomalies including neurofibromatosis, neurologic anomalies, and multiple lentiginous syndrome were not related in both cases. We report two cases of PUL having no other anomalies.

Tinea nigra is a superficial mold infection, by Phaeoannellomyces werneckii, rarely seen in Asia including Korea. Since the lesion can easily mimic a melanocytic lesion, it is important to recognize the infection before recommending unnecessary aggressive surgical procedures. We herein describe a case of tinea nigra presenting on the finger of a 41-year-old Caucasian man. Initially we diagnosed him as having lentigo, but fungal elements were detected by histopathologic examination. We recommend the routine KOH examination for the all pigmented lesion on the hands and feet.
