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.

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.

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.

Lentigo maligna melanoma and lentigo maligna are typically located on photo-exposed sites such as the head and neck, with the cheek being the most common site. Since lentigo maligna melanoma and lentigo maligna are found predominantly on such cosmetically-sensitive areas, it is critical to determine the exact histologic margin for maximal sparing of tissue and complete extirpation of the tumor. Since Mohs micrographic surgery has been recommended for tumors on cosmetically-sensitive locations where the tumor margin is indistinct, it appears to be a reasonable treatment modality for this type of tumor. We describe a case of lentigo maligna melanoma on the cheek, which was resected with Mohs micrographic surgery.

Agminated lentiginosis (AL) is a rare pigmented disorder that is characterized by numerous lentigines in a unilateral distribution or often in a segmental pattern corresponding to one or more dermatomes. AL coexists with other several diseases and some researchers have suggested it is a variant of dermatomal neurofibromatosis if AL is accompanied by cafe-au-lait (CAL) macules or neurofibromas. We report here on a case of a 12-year-old female who presented with multiple lentigines on her right neck and shoulder (the C2 and C3 dermatomes) combined with CAL macule and ipsilateral axillary freckling. On checking the family history, her mother had grouped lentigines on her right chest (the T4, T5 dermatomes). But there were no neurofibromas, Lisch nodules and neurologic or skeletal abnormalities in both of them.
