Management of the bulbous nasal tip with inadequate projection and drooping is challenging aesthetic plastic surgery. The bulbous nasal tip is influenced by several factors; 1) thick, non-elastic oily skin, 2) soft tissue bulkiness due to supratip fibrous fatty tissue, and 3) a wide intercrural angle or increased interdormal distance. Another common factor among caucasians, hypertrophic alar cartilage, is seen less in orientals. These variable factors can be corrected with various surgical maneuvers for proper tip projection and refined alar shape. All these procedures are performed through open rhinoplasty incision. The fibromuscular fatty tissue on the nasal tip is resected with subdermal tangential excision without violating the detmal blood supply. The proximal part of the lateral crus, dome and the part of medial crus which was isolated from the skin and nasal mucosa are replaced and plicated in midline in the role of a new columellar strut and skeletal support. If more skeletal supports are desired, the new columellar is reinforced with a silicone strut and conchal cartilage onlay grafts are applied. And for lengthening of the columella, a V-Y advancement incision on the columellar base with open rhinoplasty is applied. The pressure splint on the upper third of the columella and nasal tip is applied on the 7th postoperative day and maintained for two months. All procedures are focused on the preservation of catilaginous integrity and in providing skeletal support. We performed nasal tip plasty on the bulbous nasal tip and its simple technique and predictability resulted in improved nasal tip projection and contour.

The study was undertaken to clarify any quantitative abnormalities in peripheral blood T lymphocytes and T subsets, mediating cell meliated immunity, and the presence of any relation between the degree of quantitative abnormalities and extent of skin lesions and activity of disease in patients with psoriasis by monoclonal antibodies. The results were as follows. 1. Mean percentages of total and suppressor T lymphocytes in 39 patients with psoriasis are significantly decreased as compared with those in 32 controls. Mean ratio of percentage of helper T lymphocytes to that of suppressor Tlymphocytes in 39 patients with psoriasis are significantly increased as compared with that in 32 controls. 2, As classified into three groups according to extent of skin lesions (E: less than 5% E,: 5-30%, and E,: more than 30%), mean pereentages of total T lymphocytes in E, and E, psoriasis group and those of suppressor T lymphocytes in all three psoriasi., groups are significantly decreased as compared with those in controIs. Mean percentages of helper T lymphor,ytes in L psoriasis group and mean ratios of percentage of helper T lymphocytes to that of suppressor T lymphocytes in E, and E, psoriasis groups are significantly increased as compared with those in controls. 3. Cis classified into three groups according to activity of disease (A,: stationary, A,: active, peripherally spreading and A,: active, small papules spreading), mean percentage of total T lymphocytes in peripheral blood lymphocytes in A, psoriasis group and those of suppressor T lymphocytes in all three psoriasis group are significantly decreased as compared with those in controls. Mean percentages of helper T lymphocytes and mean ratios of percentage if helper T lymphocytes to that of suppressor T lymphocytes in A, and A, psorixsis groups are significantly increased as compared with those in controls. These results clarified that there are quantitative abnormalities in peripheral blood I' lymphocytes and T subsets in patients with psoriasis and the degrees of abnorrnalities are related to extent of skin lesions and activity of disease. The aanorrnalities in peri.pheral blood T lymphocytes and T subsets in patients with psoriasis seem to be attributed to primary defect of suppressor T lymphoytes.

A 52-year-old man with multiple myeloma developed cutaneous nodules while being treated with melphalan and prednisolone. A biopsy specimen showed dermal infiltration by well differentiated plasma cells similar to those found on bone marrow biopsy. The use of peroxidase anti-peroxidase to demonstrate the monoclonality or polyclonality of the cytomplasmic immunoglohulins in the tumor cells revealed a positivity for IgG and 1 chain (ie, monotypic staining). Ultrastructurally, each plasmacytoma cell contained varyting amounts of rough endoplasmic reticulum and Golgi-apparatus. The cutnneous nodules completely disappeared after radiotherapy

The immunoreactivities of surgically removed 16 cardiac myxomas were studies for factor VIII-related Ag (F VIII-RA), Ulex europaeus agglutinin I (UEA-I) and desmin alpha1-antichymotrypsin, and this study was accompained by a clinicopathologic review. More than 50% of the patients with cardiac myxomas were in their fourth and fifth decades, and cardiac myxomas were much more common in women than in men. All but on occurred in the left atrium, and the majority were attached to the atrial septum, usually in the region corresponding to the fossa ovalis. In one case, an atrial myxoma recurred 37 months after the initial excision. Microscopically, the myxomas contained a myxoid matrix composed of acid mucopolysaccharides within which were embedded polygonal cells. The cells forming both the surface and complicated vascular like channels throuhout the myxoid stroma tested positive for F VIII-RA and UEA-I. The outer cell layers of the complex vascular structures demonstrated variable staining for F VIII-RA, while isolated bundles of smooth muscle cells were present and stained for desmin. A small number of the so-called myxoma cells, immunoreactive for alpha1-antichymotrypsin which were not laden with hemosiderin pigment but were similar to histiocytes, were present particularly around the areas of hemorrhage. These findings support the current view that cellular and histologic heterogeneity arose from the divergent differentiation of multipotential mesenchymal cells. In particular, it remains to be confirmed by further study whether or not true histiocytic differentiation occurs.

Progressive cribriform and zosteriform hyperpigmentation (PCZH) is a distinctive clinical entity first described by Rower et al. in 1978. It is characterized by a single area of uniformly tan cribriform macular pigmentation in a zosteriform distriggtjpp with no preceding history of skin rash, injury or inflammation. It begins well after birth with gradual extension and is not associatad with any other cutaneous or internal abnormalities. Histologically, there is a mild increase in melanin pigment in the basal cell layer and complete absence of nevus cells. Recently, we observed clinical and histological featurea of 5 cases of PCZH. The age at onset ranged from 4 to 35 years. The lesions were unilaterally distributed on face, neck, chest, or abdomen. Histologically there was a mild increase in melanin pigment in the basal cell layer. PCZH must be differentiated from Beckers hairy nevus which begins with a unilateral lesion of irregularly macular pigmentation but occasionally it may be multiple or bilateral. In early stage, overgrowth of hairs may be absent but after a few years it is usually present. PCZH is characterized by uniformly tan cribriform pigmentation in zosteriform distribution, which is unilateral and does not cross the midline of the body. Overgrowth of hairs is absent even after a few years. So the lesions of Beckers hairy nevus previously reported, which were unilateral and did not cross the midline of the body and did not show overgrowth of hairs even after a few years, must be called progressive cribriform and zosteriforrn hyperpigmentation.
