A cutaneous horn is a general name for cornified material protruding from skin. On the other hand, polydactyly is a common congenital anomaly of the hand and foot which is characterized by extra finger or toe. A cutaneous horn might mimick polydactyly by resembling an extra toe. Hereby, we present a 72-year-old white Caucasian male with an extra toe-like projection on his fourth toe. Initially, polydactyly was suspected, however a cutaneous horn was also considered. The lesion was surgically removed. The histopathological examination of the specimen revealed hyperkeratosis, and thus confirmed the lesion to be a cutaneous horn., Funda Tamer, Mehmet Eren Yuksel, and Literatura
Nevus lipomatosus superficialis is a rare hamartomatous malformation which is composed of ectopic adipocytes in the dermis. It was first reported in 1921 by Hoffmann and Zurhelle. Two clinical forms of nevus lipomatosus superficialis have been described: classical (multiple) and solitary. Classical form of nevus lipomatosus superficialis is usually found on pelvic girdle, trunk, buttocks and thighs as soft, skin colored papules or nodules. It is usually present at birth or it appears in the first two decades of life. The solitary form of lipomatosus superficialis appears as a solitary papule or nodule on the back, scalp and arms of the patients with late onset. The lesions are usually asymptomatic, however some patients may complain about pain and itching. Malignant transformation of nevus lipomatosis superficialis has not been reported yet. Therefore, surgical intervention is only necessary for the patients who have cosmetic concerns. Recurrence after surgical removal is very rare. Perineum is an uncommon localization for nevus lipomatosus superficialis. Hereby, we report a 55-year-old Caucasian female with a 6x5,5x4 cm mass in the perineal region. The patient had cosmetic concerns, therefore she wanted the lesion to be removed surgically. The lesion was surgically removed. The histopathological evaluation of the specimen revealed nevus lipomatosus superficialis. A solitary type of giant nevus lipomatosus superficialis in the perineal region of a patient over the age of 50 is a very rare condition. Even rarely seen, nevus lipomatosus superficialis should be kept in mind in the differential diagnosis of perineal masses., Funda Tamer, Mehmet Eren Yuksel, and Literatura
Epidermal inclusion cysts are common benign cutaneous cysts which arise from hair follicles. These cysts usually present as asymptomatic, small, smooth, firm, round, slow growing swellings on hair bearing areas such as scalp, face, neck and trunk. Epidermal inclusion cysts are easily diagnosed by their clinical features. However, trichilemmal cyst, dermoid cyst, neurofibroma, hemangioma, lipoma and liposarcoma should also be kept in mind in differential diagnosis of cutaneous cystic lesions. As malignant transformation of epidermal inclusion cysts has been reported, histopathological evaluation of epidermal inclusion cysts is mandatory in order to rule out malignancy. Moreover, giant epidermal inclusion cysts with ulceration, rapid growth, resistance to treatment, recurrence and fistula drainage may have malignant potential. Therefore, epidermal cysts should be surgically removed. There are several different types of surgical techniques to remove cutaneous cysts. A proper surgical technique should facilitate the complete removal of the cyst wall to prevent recurrence. In addition, it should provide minimal scarring and a low wound infection rate. Epidermal inclusion cysts can be easily removed surgically with squeeze technique. In this technique, the cyst is squeezed out through a small incision using both index fingers. Thus, the cyst is not ruptured. The squeeze technique allows the cyst capsule to remain intact. Therefore, the risk of wound infection, recurrence and scar formation is minimized. Hereby, we present a 48-year-old male with multiple epidermal inclusion cysts on the scalp treated surgically with squeeze technique., Mehmet Eren Yuksel, Funda Tamer, and Literatura
