Three case of plexiform schwannoma displayed multinodular masses and microscopically a multicentric pattern of growth featuring Antoni A cellular component, Verocay bodies and presence of Antoni B areas. Clinically von Recklinghausen's disease was not observed in all cases. The first patient was a 17 year old male who had a protruding nodule of walnut size which was located at the dermis of the left flank for 13 years. The second case, a 25 year old male, had an irregular whitish brown multinodular mass in the choana for 5 years. The last case, a 56 year old woman, had an ovoid yellowish brown mass with multiple nodules in the retroperitoneum.

Ameloblastoma is a histologically benign tumour originating from epithelial components of the embryonic tooth, arrested developmentally prior to enamel formation. Clinically this tumour is locally invasive, potentially lethal and occasionally shows malignant features with systemic metastases. The maxilla is by far less frequently affected than the mandible. We have experienced a case of multicystic ameloblastoma originating from right maxilla. The patient was 39-year-old male who complained pain and numbness on right cheek. The patient was treated with subtotal maxillectomy by midfacial degloving approach. The final histopathologic diagnosis was a acanthomatous ameloblastoma.

Green nail syndrome is characterized by greenish discoloration of the nail. It is caused by Pseudomas aeruginosa which is an aerobic gram-negative rod found in moist environment. The most common predisposing factors are frequent exposure to water and trauma history. Herein, we report two cases of green nail syndrome who developed greenish discoloration of finger nails, which were treated by systemic levofloxacin and gentian violet application.

Desmoplastic trichoepithelioma is a rare, benign, adnexal tumor of hair follicle origin and is most commonly found on the face of young females. Clinically it presents as a solitary, asymptomatic, firm and annular plaque with a raised border. The histopathological findings show narrow strands of basaloid tumor cells with variable nests in a trabecular pattern and horn cysts in the desmoplastic stroma. This closely resembles morphea type basal cell carcinoma and microcystic adnexal carcinoma. We herein report a case of desmoplastic trichoepithelioma on the cheek of a 22-year-old man, with discussion of the significance of the immunohistochemical stains in the differential diagnosis of similar skin tumors, using antibodies for CD10, CD34, CEA, CK14, CK7 and Bcl-2.

Immature ganglion cell (IGC) is known for its relationship with intestinal motility and its impact on postoperative functional outcomes of Hirschsprung's disease (HD). There are few studies on the relationship between intestinal dysmotility and IGC in HD patients. 67 patients pathologically diagnosed with HD and who received definitive operation in Seoul National University Children's Hospital from 2010 to 2011 were included. 10 patients were excluded due to inadequate immunohistochemical staining results. The proximal end of resected ganglionic segment was evaluated with immunohistochemistry examination with MAP-2, a marker of ganglionic cells and bcl-2, a marker of IGCs The median age at operation was 155 (15-4678) day-old. 55 (96.5%) patients positive for bcl-2, were regarded as having IGC, and 2 (3.5%) patients positive for MAP-2 but negative for bcl-2, were regarded as having only mature ganglion cells. In the bcl-2 positive group, there were 7 patients (12.7%) with constipation, 15 patients (27.3%) with soiling, 3 patients (5.5%) with perianal excoriation and 6 patients (10.9%) with medication use. In bcl-2 negative group, intestinal dysmotility was not seen. There was no statistical significance in the two groups. Considering that HD is diagnosed at a young age, the rate of IGC present is very high and it might be inappropriate to relate IGC to functional outcome at young ages.

Majocchi's granuloma is a well recognized but uncommon infection of dermal and subcutaneous tissue by fungal organisms usually limited to the superficial epidermis. The organism usually associated with Majocchi's granuloma is Trichophyton(T.) rubrum, however, other dermatophytes may be the causative agent. We presented a 74-year-old female who had a well defined erythematous nodular plaque on her right cheek for 1 month. Histopathologic findings was consistent with the Majocchi's granuloma, showing perifolliculitis and granulomatous inflammation in dermis. Many fungal elements were noted in the follicular keratin plug and giant cells in the granulomatous inflammation of the perifollicular dermis in the H & E stain. But no fungal hyphae was noted in horny layer of the epidermis and a culture for the fungus was failed. The cutaneous lesion treated with terbinafine (Lamisil(R)) 250 mg and lanoconazole cream daily with cured one month later.

Inadvertent vaginal insertion of barium sulfate is an uncommon complication of a barium enema examination. In the few reported cases, venous embolizaton of barium occurred and this usually resulted in death. We present here a case of vaginal insertion of the enema catheter in a young woman, resulting in barium in the uterus, fallopian tubes and abdominal cavity, but not in the veins. After an emergency laparoscopic operation, the patient had been doing well for 6 months without evidence of complication.

Actinic granuloma develops in the chronically sun-damaged skin of the neck, face, upper chest or arms. Lesions present as skin colored to erythematous papules and plaques that coalesce to form centrifugally enlarging annular patterns. Histologically, elastolytic granuloma is formed by a dense infiltrate of giant cells and histiocytes with active phagocytosis of elastoclastic fibers on the background of solar elastosis in the upper dermis. We report a clinically rare presentation of actinic granuloma, limited to both hands of a 75-year-old female with colon cancer.
