Use of Bayes rule and MIB-1 proliferation index to discriminate Spitz nevus from malignant melanoma.
Differentiating Spitz nevus from malignant melanoma is difficult and controversial. Despite helpful lists of differential diagnostic features, uncertainty about the diagnosis often provokes some to stain the tumor for MIB-1 antibody to Ki-67 and measure the proliferation index (PI) of the tumor. Of the many reports about MIB-1 PI in Spitz nevi and melanoma, none have consolidated the informatio...
متن کاملSpitz nevus with an uncertain malignant potential.
We present the case of 10-year-old girl who have had from birth a plane tumor, of tan color, 3-4 mm of diameter, localized on the face on the cutaneous part of the superior lip. This tumor has been stabile until 8-year-old. Then, after repeated sunlight exposures, the lesion has become more stark, hemispheric in shape, has increased in size becoming about 5-6 mm, with irregular borders, and aft...
متن کاملAcral pigmented spitz nevus that clinically mimicked acral lentiginous malignant melanoma.
Pigmented Spitz nevus is a benign melanocytic skin lesion with distinct clinical features and it is frequently found on the extremities. However, it rarely occurs on acral area of the body, and such a case has not yet been fully documented. We present a case of acral pigmented Spitz nevus occurring on the foot, and this mimicked acral lentiginous malignant melanoma. Clinicians should be well aw...
متن کاملAn Orbital Malignant Melanoma Arising in Cellular Blue Nevus in a Patient with Nevus of Ota
Melanomas arising from orbital melanocytic proliferations are exceedingly rare. Many questions remain regarding their development and malignant transformation. We report on a 45-year-old Caucasian woman with a nevus of Ota that presented with visual disturbances involving her right eye and was found to have a biopsy-proven cellular blue nevus in the orbital space. Five years later, she presente...
متن کاملCommon Blue Nevus with Satellite Lesions Needs a Differential Diagnosis from Malignant Melanoma
Malignant blue nevus is rare, and a common blue nevus rarely needs a differential diagnosis from malignant melanoma. Although a melanocytic nevus with a satellite lesion is usually suggestive of a peripherally disseminating malignant melanoma, very few cases of blue nevus with satellite lesions have been reported thus far. To our knowledge, this is the seventh case of a blue nevus with satellit...
