Sorafenib is an oral, multi-targeted tyrosine kinase inhibitor with anti-angiogenic and anti-proliferative activity. It is approved for the treatment of unresectable hepatocellular and advanced renal carcinomas. Cutaneous toxicity is relatively common in patients receiving sorafenib. The most frequent cutaneous side effect is the hand-foot syndrome. Other adverse skin reactions include facial erythema, acral erythema, erythema multiforme, subungual splinter hemorrhage, stomatitis, and alopecia. In Korea, two cases of scrotal and perianal dermatitis after sorafenib therapy were reported. We report a 54-year-old male patient with a 2-week history of scrotal eczema who had been treated for chronic hepatitis type B, liver cirrhosis, and hepatocellular carcinoma. After 2 weeks of oral sorafenib (800 mg/day) administration, thick, scaly patches appeared on his scrotum. A skin biopsy specimen from these lesions revealed superficial dermal perivascular lymphocytic and neutrophilic infiltration, and dilatation of the lymphatics in the superficial dermis. The lesions improved after treatment with a topical and systemic steroid for 2 weeks. Herein, we report a rare case of scrotal erythema associated with sorafenib.

Aberrant expression of BORIS/CTCFL (Brother of the Regulator of Imprinted Sites/CTCF-like protein) is reported in different malignancies. In this study, we characterized the entire promoter region of BORIS/CTCFL, including the CpG islands, to assess the relationship between BORIS expression and lung cancer. To simplify the construction of luciferase reporter cassettes with various-sized portions of the upstream region, genomic copies of BORIS were isolated using TAR cloning technology. We analyzed three promoter blocks: the GATA/CCAAT box, the CpG islands and the minisatellite region BORIS-MS2. Polymorphic minisatellite sequences were isolated from genomic DNA prepared from the blood of controls and cases. Of the three promoter blocks, the GATA/CCAAT box was determined to be a critical element of the core promoter, while the CpG islands and the BORIS-MS2 minisatellite region were found to act as regulators. Interestingly, the polymorphic minisatellite region BORIS-MS2 was identified as a negative regulator that repressed the expression levels of luciferase reporter cassettes less effectively in cancer cells compared with normal cells. We also examined the association between the size of BORIS-MS2 and lung cancer in a case–control study with 590 controls and 206 lung cancer cases. Rare alleles of BORIS-MS2 were associated with a statistically significantly increased risk of lung cancer (odds ratio, 2.04; 95% confidence interval, 1.02–4.08; and P=0.039). To conclude, our data provide information on the organization of the BORIS promoter region and gene regulation in normal and cancer cells. In addition, we propose that specific alleles of the BORIS-MS2 region could be used to identify the risk for lung cancer.

Woringer-Kolopp disease, also known as localized pagetoid reticulosis, is a rare variant of mycosis fungoides that presents as a solitary localized hyperkeratotic patch or plaque on the extremities and follows a benign course. Effective treatments for Woringer-Kolopp disease include skin-directed therapies such as topical nitrogen mustard, high-potency topical steroids, and phototherapy. Surgical excision has been pursued in cases of small, localized lesions. A 39-year-old man presented with a 3-month history of an asymptomatic plaque on his hand. Physical examination showed a 10-mm-diameter solitary round erythematous hyperkeratotic plaque with a slightly raised edge on the dorsum of his left hand. A skin biopsy revealed that numerous atypical lymphocytes had infiltrated the upper dermis and expanded into the epidermis with a pagetoid pattern. These atypical pagetoid cells were strongly positive for CD3, CD8, and T-cell intracellular antigen-1; focally positive for CD4; and negative for CD20, CD30, and CD56. A subsequent general examination revealed no evidence of systemic involvement and the lesion was treated with surgical excision. Here we report a rare case of Woringer-Kolopp disease.

Bowen's disease is a squamous cell carcinoma in situ and has the potential to progress to a squamous cell carcinoma. The authors treated two female patients (a 39-year-old and a 41-year-old) with Bowen's disease in the vulva area using topical photodynamic therapy (PDT), involving the use of 5-aminolaevulinic acid and a light-emitting diode device. The light was administered at an intensity of 80 mW/cm2 for a dose of 120 J/cm2 biweekly for 6 cycles. The 39-year-old patient showed excellent clinical improvement, but the other patient achieved only a partial response. Even though one patient underwent a total excision 1 year later due to recurrence, both patients were satisfied with the cosmetic outcomes of this therapy and the partial improvement over time. The common side effect of PDT was a stinging sensation. PDT provides a relatively effective and useful alternative treatment for Bowen's disease in the vulva area.

Perineurioma is a rare benign peripheral nerve sheath tumor, composed uniformly of perineurial cells. Soft tissue perineurioma primarily arises within the subcutaneous tissue of extremities and trunk as a painless solitary nodule, and should be distinguished from dermatofibroma, neurofibroma, dermatofibrosarcoma protuberans, meningioma and so on. A 25 year-old female is presented with three small asymptomatic papules on the third left finger which were found 3 years ago. Punch biopsy was performed on all of the papules. Microscopic examination demonstrated well-demarcated tumor within dermis, and proliferation of spindle cells with wavy nuclei and elongated bipolar cytoplasmic process, arranged in a whorled pattern. According to immunohistochemical analysis, the tumor cell showed positivity for epithelial membrane antigen, but negativity for S-100 protein, factor XIIIa, CD34, and smooth muscle actin. The diagnosis of soft tissue perineurioma was being made. We report this rare case of perineurioma presented as multiple papules localized within dermis of the digit.

Pityriasis rubra pilaris (PRP) is a chronic papulosquamous disorder of unknown etiology, which may pose therapeutic challenges. There is currently no universally effective treatment for PRP, and some cases are resistant to multiple topical and systemic therapies. Systemic retinoids, methotrexate, several immunosuppressive agents and phototherapy have all been used with varying degrees of success. Recently, a few reports have appeared in the literature, concerning the use of biologics in combination therapies and/or in refractory PRP cases. We report a case of PRP similar to type II with juvenile onset, which was recalcitrant to traditional topical and systemic therapy. He was successfully treated with anti-TNF-alpha monoclonal antibody, infliximab. The patient showed resolution with minimal disease activity, and was maintained on acitretin and emollients. The response to infliximab in our patient and in the previously reported cases confirms a role of anti-TNF-alpha therapy as an effective option in the treatment of PRP.

Eccrine angiomatous hamartoma (EAH) is a rare benign disease that is characterized by an abnormal proliferation of eccrine glands and vascular elements. It is generally congenital, but it can appear before puberty. It usually presents as a single plaque or nodule, but multiple patch-like lesions are also possible. EAH is mostly asymptomatic, but it is sometimes associated with pain or hyperhidrosis. It generally does not require aggressive treatment, but the lesion can be excised due to pain, enlargement and cosmetic reasons. A 3-week-old Korean female presented with a hemorrhagic skin lesion on the right foot since birth. There was no specific birth history. The lesion first appeared on the third toe of the right foot and quickly spread to almost half of the right foot. Histopathology examination revealed acanthosis in the epidermis and a proliferation of eccrine ducts, glands and capillaries. The eccrine glands were immunohistochemically-positive for carcinoembryonic antigen.
