We present two oases of Eruptive Vellus Hair Cysts(EVHC) in 30- year-old and 27- year old women. They had 6 to 10 discrete, asymptomatic, brown or reddish brown papules on the neck, axilla, chest and extremities. The clinical impressions were epidermal cyst and steatocystoma multiplex espectively, but histopathological exarnination revealed smal1 cysts in middermis containing numerous vellus hairs cut transversely or obliquely and surrounding granulomatous foreign body reaction typical to EVHC. Transepithelial elimination was not found.

Lymphomatoid papulosis is a disease; clinically benign, histologically malignant. Clinically, it may sirnulate pityriasis lichenoides et varioliformis acuta, but histologically it suggest malignant lympboma due to the presence of polymorphous lymphoid infiltrate consisting of sma11 lymphocytes intermingled with conspicuous large atypical cells. Recently, many autbors consider lymphornatoid papulcsis as a Cutaneous T-cell lymphoma, and malignancy has been reported to develop in some patients. We experienced a case of lyrnphomatoid papulosis in 26-year-old woman and treated with PUVA successfully. PUVA treatment may be proven useful in controlling this disease and it rnay also inhibit the development of malignancy.

Generalized pustular psoriasis which is originally described by von Zumbusch in 1910, is the most intense form of the acute exanthematic variant among psoriasis. It is to be occured as a rare disease and the familial occurrence rarely has been reported. Many therapeutic attempts have been rnade to bring the condition under control, but none has unequivocally proven to alter its courae decisively. We present two cases of generalized pustular psoriasis in brother and sister (16 year-old male, 19 year-old female) which were treated successfully by pbotochemotherapy (PUVA).

Fine needle biopsy of nodules on the thyroid is simple diagnostic method and it is generally a safe procedure. The main side effect is pain and hematoma. Secondary hemangioma development after biopsy is extremely rare. A 63-year-old woman presented with a 5-year history of solitary erythematous papule on neck. Spontaneous bleeding recorded six times within 5 years. There is not vascular anastomosis in ultrasonographic imaging. A histopathologic study showed vessel-like arteriole around small veins in dermis. No arteriovenous hemangioma case has been previously reported to be related to fine needle biopsy. Our case showed possibilities of arteriovenous hemangioma developments after fine needle biopsy.

Trichoblastoma is a benign cutaneous neoplasm that consists of follicular germinative cells. There have only been a few case reports describing the malignant counterpart of trichoblastoma. We report trichoblastic neoplasms that show histological features of malignancy. The histological sections revealed locally aggressive neoplasms showing prominent differentiation towards hair germ and follicular sheath with formation of papillary mesenchymal bodies and follicular bulb-like structures. The tumor was widely excised with a clear margin. No sign of recurrence has been noted 1 year later.

Hidroacanthoma simplex, eccrine poroma and dermal duct tumors have recently come to be viewed as variants of benign poroid neoplasia, due to their similar histopathologic and cytologic features. Some authors have reported the association of two or three of these tumors in a single lesion. We herein report a patient with two subtypes of poroma in a single lesion.

Blue nevi are usually solitary, but they may be multiple and form a plaque composed of multiple papules or nodules with an intervening flat area of blue coloration. It looks like a benign and asymptomatic lesion. However, because of its rarity, no definitive prognosis can be given. An 18-year-old male presented with a 5 x 4 cm-sized, speckled blue-black tumor on his posterior neck, which had existed since birth. Histopathologic examination showed clumps of melanocytes intermingled with irregularly arranged collagen bundles in the mid and lower dermis, with some extending to the subcutaneous tissue. We diagnosed the lesion as a plaque-type blue nevus, based on histopathologic findings of common blue nevus.

Basal cell carcinoma (BCC) represents the most common cutaneous malignancy in caucasions. Most of the tumors usually occur on sun-exposed skin, and they are small and easily treated. Giant BCC is a rare variant of this tumor and is defined as a lesion greater than 5 cm at its largest diameter. For the development of giant BCC, several risk factors, including patient neglect, aggressive histological features and long duration, have been identified. We observed a very large BCC on the face and scalp of an elderly woman. She had been reclusive for a long time, and this problem might have played a crucial role in the development of the giant BCC.
