Pleomorphic adenoma in the auricle.

Pleomorphic adenoma (PA) is a rare tumor of the skin that may arise from either the apocrine or the eccrine glands. Only 4 cases of PA in the auricle have been reported. We experienced the case of a 40-year-old woman who had a slowly growing, nontender auricle mass for 3 years.

Successful replantation of an amputated earlobe by microvascular anastomosis.

In the microsurgical area, replantation of ear amputation by microvascular anastomosis is considered to be the best method in terms of texture, color, and shape. Only a few cases of successful ear replantation with microvascular anastomosis have been reported because the size of the vessels is very small, and identifying appropriate vessels for anastomosis is difficult. Furthermore, most cases were total or subtotal (upper two thirds of the ear) amputations, and they were successfully reconstructed by replantation.

Fibrolipoma of the tip of the nose.

Fibrolipoma is a rare benign tumor that usually presents as an asymptomatic, slowly growing mass with a firm or soft consistency clinically. Histopathologic findings show the proliferation of normal mature fat and fibrous tissue. We report a first case of the fibrolipoma of the nasal tip in a 24-year-old man.

Multiple huge epidermal inclusion cysts mistaken as neurofibromatosis.

Epidermal inclusion cyst is one of the common benign soft tissue tumors, and it can be easily confirmed and treated by surgical excision. We experienced a patient who had multiple masses on the face and scalp region, and the masses had been misdiagnosed as neurofibromatosis because of accompanying mental retardation. We would like to introduce a case of clinical diagnosis error caused by the lack of radiologic evaluation and pathologic confirmation.

One-stage skin grafting of the exposed skull with acellular human dermis (AlloDerm).

In cases of soft tissue defects in which the calvaria is exposed, the use of flap is generally considered. However, in cases in which patients' general status is poor or vascular insufficiency is present, the use of flap becomes difficult. A 90-year-old male patient visited our outpatient clinic with a chief complaint of scalp defect accompanied by calvarial exposure after falling from an escalator.

Reconstruction of scalp defect after Moyamoya disease surgery using an occipital pedicle V-Y advancement flap.

Scalp necrosis is an infrequent complication of Moyamoya disease surgery, which is more prevalent in the parietotemporal area. Because scalp vascularity is severely compromised after Moyamoya disease surgery, reconstruction of defects with local scalp tissue is challenging. To cover defects, a flap is needed that is highly vascularized and has great mobility and territory to avoid existing scars.
