Lichen planus is a chronic papulosquamous disease that affects the skin and mucous membranes. It is characterized by pruritic violaceous papules that are most commonly seen on the extremities of middle aged adults, but the elderly are rarely affected. Hypertrophic lichen planus usually occurs on the extremities and especially on the shins, and it tends to be the most pruritic variant. An 82-year-old female presented with severe pruritic multiple papules and plaques on the both the upper and lower extremities for 1 year. At first, the lesions began as small, polygonal papules that formed verrucous plaques over several months. Histopathologic examination showed marked hyperkeratosis, irregular acanthosis and wedge-shaped hypergranulosis. The vacuolar alteration and the lymphocytic inflammatory infiltrate were accentuated at the base of the rete ridge. From these findings, we diagnosed these lesions as hypertrophic lichen planus. The lesions were treated with topical steroid and intralesional injection of steroid, and they were slightly improved after 2 months of therapy. (Korean J Dermatol 2011;49(1):82~85)

A calcifying aponeurotic fibroma is a rare benign fibrous tumor with well-characterized histopathological features. Calcifying aponeurotic fibromas are generally slowly-growing lesions related to tendons and aponeuroses in the distal extremities of children and adolescents. While the neoplasm is usually asymptomatic, cases of progressive local discomfort have been reported. The exact etiology of this neoplasm is unknown, and there is frequently no history of trauma or local irritating factors. A 10-year-old female presented with a 2.5×2.0 cm, subcutaneous mass on the right sole 4 years after she bumped against a table. The histopathologic examination showed a poorly circumscribed fibrotic mass with foci of chondroid differentiation and calcification. These findings were consistent with the diagnosis of a calcifying aponeurotic fibroma. After total excision of the mass, there has been no recurrence of the lesion in 8 months of follow-up.

Eosinophilic cellulitis is also called Wells` syndrome, and this is an acute pruritic dermatitis that resembles cellulitis. It usually appears as well-circumscribed erythematous plaques, but bullous lesions have rarely been reported. There are several precipitating factors, including drugs, arthropod bites, viral infections, parasitic infestations, leukemia and other malignancies. A 21-year-old male presented with a mildly pruritic vesiculobullous eruption on the dorsum of left foot after he had been pricked by a twig. Histopathologic examination showed intraepidermal blisters and spongiosis of the epidermis and a mixed inflammatory cell infiltration that consisted mostly of eosinophils throughout the dermis. These findings were consistent with the diagnosis of bullous eosinophilic cellulitis. He was treated daily with prednisolone 30 mg and the lesions rapidly resolved. There has been no recurrence of the lesions for 1 year of follow-up. (Korean J Dermatol 2010;48(12):1128∼1131)

Cutaneous metastasis originating from lung cancer is relatively rare and accounts for only 0.5~6.7% of of lung cancer metastases. In general, there is a histomorphologic resemblance between primary carcinoma and cutaneous metastatic carcinoma. A 45-year-old woman presented with a painless 0.8 cm erythematous nodule on her left shoulder. During the past 3 years, she had been receiving chemotherapy for the treatment of lung adenocarcinoma with bone metastases. A histopathological examination of the skin lesion showed adenocarcinoma and squamous cell carcinoma components, which were compatible with adenosquamous carcinoma. Herein, we report an interesting case of adenosquamous carcinoma showing cutaneous metastasis, which is a different pathologic subtype from primary lung adenocarcinoma.

Glomus tumors are benign cutaneous neoplasm, occurring in the vascular hamartomatous tubercles of the glomus body, which is a myoarterial apparatus typically found in the reticular dermis of the skin. Histopathologically, glomus tumors are composed of neoplastic cells that resemble normal glomus cells, arranged around a varying number of thin-walled, sometimes branching capillaries. Immunohistochemically, neoplastic cells in glomus tumors clearly exhibit smooth muscle characteristics with expression of muscle-specific actin and α-smooth muscle actin; whereas, the expression of CD34 is rare. In this report, we present two cases of benign glomus tumors on the subungual area and palm. Tumor cells of glomus tumor in two patients were both positive for smooth muscle actin (SMA) and CD34 immunohistochemical staining. We thought that coexpression of SMA and CD34 adds support to the interpretation of these lesions as a family of perivascular neoplasms. (Korean J Dermatol 2012;50(11):969∼ 973)
