Pigmented Bowen's disease is characterized by microscopically increased melanin pigment in the epidermis and/or papillary dermis in addition to the typical findings of Bowen's disease. This disorder is infrequently reported and represents less than 2% of cases of Bowen's disease. Pigmented Bowen's disease is often confused clinically with pigmented lesions, such as seborrheic keratosis, melanocytic nevus, pigmented basal cell cacinoma and superficial spreading melanoma. A 74-year-old man presented with a black hyperkeratotic nodule overlying a solitary dark brownish patch on the scalp, this was clinically diagnosed as seborrheic keratosis. Histopathologic examination revealed pigmented Bowen's disease. We, herein, report an unusual case of pigmented Bowen's disease, which is the first reported case to have occurred on the scalp and to clinically resemble seborrheic keratosis.

Seborrheic keratosis is a benign epidermal neoplasm, but malignant transformation may, rarely occur. We, herein, report an unusual case of Bowen's disease arising in seborrheic keratosis. A 74-year-old man presented with multiple grouped erythematous to dark brownish papules on the left shoulder for 9 months. Histopathologic examination taken from the largest papule of the left shoulder revealed the findings of seborrheic keratosis connecting with Bowen's disease. This case supports the possibility of malignant transformation of seborrheic keratosis.

A 21-year-old man presented with a solitary 14x10cm sized slightly elevated firm plaque with partial hair loss on the right parietal scalp, which he had had since birth. Histopathologic examination revealed typical findings of congenital intradermal nevus. As a preoperative procedure a 300cc capacity crescentic expander was placed under the uninvolved scalp. Inflation and expansion of uninvolved left parietal scalp with saline over a 10-week period allowed excision of a 14x10 cm sized area of medium-sized congenital intradermal nevus. No hematoma or infection of the expanded skin occurred. We, herein, report an unusual case of diffuse congenital, nonpigmented, intradermal nevus with partial alopecia on the scalp, which was successfully treated with complete excision used by tissue expander.

OBJECTIVE: To evaluate transverse skeletal and dental changes, including those in the buccolingual dental axis, between patients with skeletal Class III malocclusion and facial asymmetry after bilateral intraoral vertical ramus osteotomy with and without presurgical orthodontic treatment. METHODS: This retrospective study included 29 patients with skeletal Class III malocclusion and facial asymmetry including menton deviation > 4 mm from the midsagittal plane. To evaluate changes in transverse skeletal and dental variables (i.e., buccolingual inclination of the upper and lower canines and first molars), the data for 16 patients who underwent conventional orthognathic surgery (CS) were compared with those for 13 patients who underwent preorthodontic orthognathic surgery (POGS), using three-dimensional computed tomography at initial examination, 1 month before surgery, and at 7 days and 1 year after surgery. RESULTS: The 1-year postsurgical examination revealed no significant changes in the postoperative transverse dental axis in the CS group. In the POGS group, the upper first molar inclined lingually on both sides (deviated side, −1.8°± 2.8°, p = 0.044; nondeviated side, −3.7°± 3.3°, p = 0.001) and the lower canine inclined lingually on the nondeviated side (4.0°± 5.4°, p = 0.022) during postsurgical orthodontic treatment. There were no significant differences in the skeletal and dental variables between the two groups at 1 year after surgery. CONCLUSIONS: POGS may be a clinically acceptable alternative to CS as a treatment to achieve stable transverse axes of the dentition in both arches in patients with skeletal Class III malocclusion and facial asymmetry.

Transmission electron microscopy of an Acanthamoeba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae. The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/L1, the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, previously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 in aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38 x 0.50 microns. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included in lacunaelike structure.
