Abstract :
Blue nevi are a subset of melanocytic proliferations of embryonic neural crest origin containing cells similar to dendritic melanocyte precursors. Cervical Blue Nevi are benign pigmented melanocytic lesions that are rarely detected and usually seen in middle-aged women. It has various shapes such as dentridic, spindle-shaped, oval or polyhedral forms. Blue or blue-black macules or papules are common on the dorsal hands and feet, neck, and trunk [1]. Also, interestingly, in other places where melanocytes do not exist. It can also be found; in oral mucosa, sclera, uterine cervix, vagina, prostate, spermatic cord, pulmonary hilus, conjunctiva, maxillary sinus, mammary lymph nodes [1], [2]. In female genital tracts, it most commonly occurs in the uterine cervix. It is usually detected incidentally on microscopic examinations. Clinically, it can be seen as a blue-black spot on the posterior wall of the cervix. Various authors have described these lesions as <0.5 cm small and solitary blue-black macules on the endocervix. Here, we presented the histopathological features and differential diagnosis of a blue nevus detected in the pathology material after hysterectomy in a 43-year-old patient, on examples from the literature.
