ABSTRACT
Plantar vein thrombosis is a rare condition, which can cause foot pain when walking. The cause of thrombosis is not clear. We experienced a case of plantar digital vein thrombosis which occurred in the left big toe. The patient was a 35-year-old man who presented with foot pain when during walking since one month ago. There was a solitary skin colored nodule on the left big toe. Skin punch biopsy was performed, and the diagnosis of plantar digital vein thrombosis was made. Plantar digital vein thrombosis is a very rare cause of toe pain. We herein report this interesting case.

Chronic mucocutaneous candidiasis is a rare syndrome characterized by persistent and refractory infection of the skin, nail and mucosal tissue by yeasts of the genus Candida. A 70-year-old woman presented with the following skin lesions: ill-defined annular shaped whitish macules on the upper and lower lips accompanying dryness, pain and burning sensation, and yellowish discoloration with onycholysis of the right 4th finger nail. The upper lip lesion showed histopathologic feature of band-like infiltration of lymphocytes in the upper dermis, consistent with lichen planus. But, systemic glucocorticoid was not effective in treating erosive lip lesions. KOH examination and fungal culture of specimens from the upper lip showed hyphal elements and growth of Candida albicans, respectively. Antifungal agent was administered. After the oral medication, skin lesions were improved but there was repeated recurrence. We report a case of chronic mucocutaneous candidiasis misdiagnosed as lichen planus.

Fluoroscopy-induced chronic radiation dermatitis (FICRD) is a cutaneous disorder that results from prolonged exposure to ionizing radiation during interventional procedures. With the expanded use of interventional procedures, there is increased fluoroscopic exposure. However, diagnosis and treatment of such disorder remain difficult. Herein, we report on a case of FICRD that occurred in the right subscapular area.

BACKGROUND: The histologic distinction of dermatofibrosarcoma protuberans (DFSP) and dermatofibroma (DF) may be difficult, especially in the case of DF extending into the subcutaneous fat. CD34 and Factor XIIIa stains are commonly used in distinguishing the DF from DFSP, but is not always helpful. There are no studies regarding the clinicopathologic comparison of DF and DFSP. OBJECTIVE: The aim of our study was to evaluate the clinicopathologic characteristics and differences between the DF and DFSP. METHODS: Retrospective analysis was performed by reviewing the clinicopatholgic records of 40 patients who were diagnosed with DF, and 11 patients who were diagnosed with DFSP, from 1998 to 2012 in Hallym University Medical Center. RESULTS: The ratio of male to female patients in DF and DFSP were 1:2.1 and 1:1.8, respectively. Disease onset ages were 32.6 years and 34.4 years, respectively. The average size was 0.8 cm and 2.0 cm, respectively. The most frequent location was the lower extremity and the trunk, respectively. No symptom was most common subjective symptom in both DF and DFSP. Most of DF presented as brown colored papules and the lesions of DFSP were reported mainly as brown plaques. Histopathologically, the 40 cases of DF were classified as 24 fibrous types, 12 cellular types and 4 aneurysmal types. Of the 11 DFSP, two cases were classified as myxoid type, one case as pigmented lesion (Bednar tumors) and one case as fibrosarcomatous type. Histopathologic findings of the DF showed more significant epidermal hyperplasia, basal hyperpigmentation and collagen trapping, compared to that of the DFSP. The subcutaneous extension and honeycomb pattern were significantly more present in DFSP than in DF. The immunoreactivity of CD34 in DFSP was generally strong and diffuse, in contrast to absent or focal staining seen in DF. CONCLUSION: We conclude that several cilinicopathologic features, including size, location, epidermal and tumoral component, and immunostaining, for CD34 can be used to distinguish DF from DFSP. Further research regarding the characteristics and differences between DF and DFSP should be performed on larger number of cases.

Balloon cell melanoma, an uncommon histopathological variant of malignant melanoma, was first described by Gardner and Vazquez in 1970. This condition is histopathologically characterized by the presence of balloon cells with varying sizes and atypical nuclei. An 84-year-old woman presented with a solitary, dome-shaped, walnut-sized, brownish nodule on the posterior aspect of the left ear with bleeding, having only detected the nodule 2 weeks prior. Histopathologically, the lobulated tumor mass revealed copious melanin pigment and many balloon cells with clear cytoplasm, atypical nuclei, and variable size. Immunohistochemically, the tumor mass showed positive reaction to S-100 protein and HMB 45 staining. We herein report a typical case of balloon cell melanoma, which developed primarily on the skin.

Trichoblastoma is a rare, benign skin tumor of adnexal origin that differentiates toward the hair germ, the embryonic precursor of a hair follicle. Clinically, it presents as a slow growing, solitary, well-circumscribed nodule located predominantly in the head and neck area, with a predilection for the scalp. The trunk, proximal extremities and perianal and genital regions may also be affected. We herein present a case of trichoblastoma which occurred on the trunk as a solitary subcutaneous mass with a central tiny pore in 53-year-old man.

Milia are small, superficial keratin cysts believed to be derived from the pilosebaceous follicle, which arise most commonly on the cheeks and eyelids. We report a case of milium occurring on the glans penis in a 18-year-old man, who had a solitary dome-shaped, 2x2 mm sized, yellowish papule. The histopathological examination showed a small keratin-filled, intradermal cyst. The cyst was lined by a stratified epithelium that was a few cell layers thick. This is the first case report in the Korean dermatological literature of milium occurring on the glans penis without coexistence of other dermatoses.

Pilonidal sinus is one of a follicular occlusion tetrad, and is a chronic inflammatory disease that is associated with hair; a midline hairy patch or pit in the sacral region with a sinus orifice in the bottom, or a cyst beneath it, in which hair is growing. The exact pathogenesis of pilonidal sinus remains unknown, but hair insertion may be the essential cause of the disease. It is usually treated by radical excision, marsupialization or incision and curettage. However, these surgical options often lead to a high recurrence rate, especially for hirsute patients. Wide excision and simple primary closure of the pilonidal sinus is an easy, simple method and the recurrence rate is low. We report here the case of an 18-year-old male patient with recurrent pilonidal sinus mimicking inflammatory epidermal cyst. The pilonidal sinus was treated by wide excision and primary closure.

Becker's nevus is a relatively common acquired focal epidermal melanotic hypermelanosis usually found in the region of the shoulder girdle of young men. Various skeletal malformations and cutaneous dermatoses have been reported in Becker's nevus. Osteoma cutis is a rare disorder characterized by compact bone formation in the dermis or subcutaneous tissue. Secondary ossification on nevi has been reported, but not with Becker's nevus. Herein, we report a case of Becker's nevus with accompanying osteoma cutis in an 18-year-old female.

Sinusoidal hemangioma is a distinctive subset of a group of lesions known collectively as cavernous hemangiomas. Clinically, it develops in adults, predominantly females, and presents as a solitary, painless, bluish, deep dermal or subcutaneous nodule. Lipoma is the most common benign soft tissue tumor. Lipoma is distinguished from sinusoidal hemangioma on both clinical and histological grounds. Several studies have suggested that adipocytes originate from perivascular cells during adipogenesis. Angiogenic cytokines released by adipocytes play a role in the vasoproliferative response. The rearrangement or loss of chromosome 13 can also be associated with hemangioma. However, no previous cases of sinusoidal hemangioma have been associated with benign tumors like lipoma. Here, we describe an unusual case of sinusoidal hemangioma that occurred together with a lipoma on the right upper arm of a 43-year-old male.
