Abstract
Skin meta stases (SM) are infrequent secondary locations of deepneoplasia that can sometimes be indicative of primary cancer. They represent 0.2 to 10% of metastases from solid tumors [1]. The most frequent primary tumors in men were carcinoma of the lung (24%), carcinoma of the large intestine (19%), melanoma (13%), and squamous cellcarcinoma of the oral cavity (12%). The most common primary tumors in women were carcinoma of the breast (69%), carcinoma of the large intestine (9%), melanoma (5%), and carcinoma of the ovary (4%) [2]. The incidence of cutaneous involvement by all urolo gicalm alignanciesis 1.1% to 2.5% [3]. The kidneyis the most common organ to serve as a source of meta stasis to the skin [4]. Bladder cancers are lesslikely to metastasize to the skin We report a new case of skin metastases presenting as a large tumor in the thoraciclevel in a patient followed for a urothelial carcinoma of the bladder.

At the dermoscopy we had pigmented areas without structures, with the presence of a polymorphic vascularization made of arborising vessels as well as tortuous vessels (Figure 2), in front of this aspect associated with the clinical context we first thoughtto a skin metastasis bladder tumor, and a skin biopsy was performed confirming this diagnosis
Summary
Skin meta stases (SM) are infrequent secondary locations of deepneoplasia that can sometimes be indicative of primary cancer. They represent 0.2 to 10% of metastases from solid tumors [1]. Bladder cancers are lesslikely to metastasize to the skin We report a new case of skin metastases presenting as a large tumor in the thoraciclevel in a patient followed for a urothelial carcinoma of the bladder. The patient wasthen put on neoadjuvant chemotherapy, but hew as lost to follow-up and presented him self after 5 months, with extension of the tumor to the gall bladder, and the urethral masses, the internal obturator muscle and bilateral externaliliac lymphadenopathy, as well as adrenal metastasis, with an examination of oncologists the presence of a skin tumor in the right thoracic level, a dermatological opinion was requested. The patient was kept on palliative chemotherapy based on cisplatin + gemcitabine, and died 2 monthslater
