Kronik Venöz Yetmezliğe İkincil Gelisen Merkel Hücreli Karsinom, Nadir Bir Vaka

Merkel hücreli karsinom (MHK) genellikle ileri yaslarda ve günese maruz kalınan vücut bölgelerinde ortayan çıkan nadir bir cilt tümörüdür. Tümör agresif seyirli olup, tanıda gecikme olması durumunda tedavisi zordur ve prognozu kötüdür. MHK, kronik venöz yetmezlik zemininde ve alt ekstremitede nadiren görülür. Bu olguda 85 yasında bir erkek hastada sağ bacakta, kardiyak by-pass cerrahisi için safen ven greft alınma operasyonu sonrası olusan kronik venöz yetmezlik zemininde gelisen ülsere ve ciltten kabarık bir lezyondan alınan biyopsi sonucu merkel hücreli karsinom tanısı konulmustur. Kronik venöz yetmezlik zemininde sıklıkla gelisebilecek venöz ülserler ve diğer cilt lezyonlarının ayırıcı tanısında MHK gibi cilt maligniteleri akılda tutulmalıdır.

Merkel Cell Carcinoma Secondary to Chronic Venous Insufficiency, A Rare Case

Merkel cell carcinoma (MCC) is a rare skin tumor that usually develops in elderly and sun- exposed body regions. The tumor is aggressive in nature, and in the case of delayed diagnosis, the treatment is difficult and the prognosis is poor. MCC is rarely seen on the ground of chronic venous insufficiency and on the lower extremity. In this case, an 85-year-old male patient was diagnosed with Merkel cell carcinoma in the right leg, biopsy specimen taken from an ulcer and a raised lysole from chronic venous insufficiency after cardiac bypass graft surgery for cardiac bypass surgery. Skin malignancies such as MCC should be kept in mind in the differential diagnosis of venous ulcers and other skin lesions that may develop frequently on the basis of chronic venous insufficiency.
