Bortezomib (Velcade(R)) is proteasome inhibitor that is used as a first-line therapy for multiple myeloma. It can cause gastrointestinal, hematologic, and neuromuscular side effects, and a cutaneous reaction is one of its common adverse reactions. To date, several bortezomib-induced cutaneous adverse reactions have been reported, including folliculitis-like rash, pruriginous rash, purpuric rash, mouth swelling, stomatitis-mucositis, edema in the lower limbs, telogen effluvium, and vasculitis. In the Korean literature, only one case of vasculitis has been reported earlier. Two patients have presented with multiple plaques on the trunk at our clinic. The lesions developed several days after bortezomib chemotherapy, and disappeared spontaneously in about 1 week. Herein, we report bortezomib-induced drug eruption presenting as multiple plaques on the trunk with a review of the relevant literature.

7.A Novel Approach for Full-Thickness Defect of the Nasal Alar Rim: Primary Closure of the Defect and Reduction of the Contralateral Normal Ala for Symmetry.

In full-thickness defects of the nasal alar rim, to achieve projection and maintain airway patency, cartilage graft is frequently needed. However, cartilage graft presents a challenge in considerations such as appropriate donor site, skeletal shape and size, and healing of the donor area. To avoid these demerits, we tried primary closure of alar rim defects by also making the contralateral normal ala smaller. We treated two patients who had a full-thickness nasal alar defect after tumor excision. Cartilage graft was considered for the reconstruction. However, their alar rims were overly curved and their nostril openings were large. To utilize their nasal shape, we did primary closure of the defect rather than cartilage graft, and then downsized the contralateral nasal ala by means of wedge resection to make the alae symmetric. Both patients were satisfied with their aesthetic results, which showed a smaller nostril and nearly straight alar rims. Moreover, functionally, there was no discomfort during breathing in both patients. We propose our idea as one of the reconstruction options for nasal alar defects. It is a simple and easy-to-perform procedure, in addition to enhancing the nasal contour. This method would be useful for patients with a large nostril and an overly curved alar rim.

Background:
Pemphigus is an autoimmune blistering disease characterized by the production of autoantibodies against desmosomal proteins. Owing to its high mortality rate, prompt and accurate diagnosis of pemphigus is crucial.
Objective:
To determine the positivity rates of immunoblotting in patients diagnosed with pemphigus using clinical, histopathological, direct immunofluorescence (DIF), and enzyme-linked immunosorbent assay (ELISA).
Methods:
We retrospectively evaluated 84 patients diagnosed with pemphigus between 2001 and 2021 at the Chonnam National University Hospital in Gwangju, Korea.
Results:
Among the 55 patients with pemphigus vulgaris included in the immunoblotting study, 46 (83.6%) exhibited positive findings for the 130 kDa band. Of the 29 patients with pemphigus foliaceus, 17 (58.6%) showed positive findings for the 160 kDa band. In cases where autoantibodies were difficult to detect with negative DIF and ELISA results, immunoblotting aided in the diagnosis of 18.2% of pemphigus vulgaris cases and 6.9% of pemphigus foliaceus cases.
Conclusion
Immunoblotting can serve as an alternative diagnostic method for patients with mild-to-moderate disease or those who have undergone treatment, especially when DIF or ELISA tests yield negative or atypical results.

Morgellons disease is a rare disease with unknown etiology. Herein, we report the first case of Morgellons disease in Korea. A 30-year-old woman presented with a 2-month history of pruritic erythematous patches and erosions on the arms, hands, and chin. She insisted that she had fiber-like materials under her skin, which she had observed through a magnifying device. We performed skin biopsy, and observed a fiber extruding from the dermal side of the specimen. Histopathological examination showed only mild lymphocytic infiltration, and failed to reveal evidence of any microorganism. The polymerase chain reaction for Borrelia burgdorferi was negative in her serum.

A 21-year-old woman found to be hypertensive was referred for hypertension. On examination, blood pressure was 170/110mmHg in the right arm, 160/100mmHg in left arm,and 120/70mmHg in legs. A grade 2/6 systolic ejection murmur was present at the left upper sternal border, and a chest x-ray revealed a rib notching on the inferior margin of 4th rib. Two-dimensional echocardiogram showed the coarctation of aorta beyound the origin of the left subclavian artery. Biplane TEE demonstrated a discrete narrowing of the descending aorta at the site of coarctation. The blood pressure was 169/86mmHg in ascending aorta and 118/84mmHg in descending aorta. Aortogram showed a localized coarcted aortic segment of 7mm in diameter and 5mm long just distal to the left subclavian artery. Balloon coarctation angioplasty was performed with 7F 30x15mm pediatric balloon dilatation catheter. Balloon position was confirmed on fluoroscopy by the hourglass appearance of the balloon inflation and thereafter, the balloon was inflated until the waist of the balloon disappeared. After procedure, a pull back pressure tracing across the coarctation of aorta revealed no pressure gradient between ascending and descending aorta with 141/90mmHg. Aortogram showed an increase in diameter of the coarctation of aorta to 18mm with aneurysmal formation. 3 months later, follow up aortogram showed no significant change in diameter of coarctation of aorts or aneurysmal formation. Nonsurgical balloon coarctation angioplasty appears to be an alternative therapy for the coarctation of aorta in adults.
