Hemangioma can be misdiagnosed. In our case the lesion was suggestive of a melanoma of the leg in a young patient. Indeed, the location of hemangioma in the limb is extremely rare and the and the literature most often reports the location of the upper limb. The largest hemangioma described was 10 cm in diameter In our patient, the size was 5.5×5 cm which makes our case interesting. In our case, the appearance, location and evolutionary history of the lesion were mistaken for a melanoma. Cavernous hemangioma is a rare, malformation that is difficult to diagnose. It is most of deep localization, namely the nervous system, the bone and the muscle. We report a case of a giant hemangioma of the leg mimicking a melanoma. Key words: Cavernous hemangioma; Giant hemangioma; Limb hemangioma

Mycosis fungoides (MF) has a wide spectrum of presentation. Its clinic is polymorphic, leading to several clinical variants. Chronic diffuse hyperpigmented lesions can be found in MF. We describe a case of lichenoid type mycosis fungoides. It differs from the classical form by the presence of erythematous and or pigmented scaly papules and not pruritic. The clinicopathological correlation is thus essential to establish a precise diagnosis of MF and its clinical simulators. Key words: Mycosis fungoides, Cutaneous T lymphoma, Chronic lichenoid keratosis
