Lymphomatoid papulosis (LyP) is a chronic lymphoproliferative disorder characterized by the appearance of crops of papules, nodules, and sometimes large plaques at different stages of development. Pseudocarcinomatous hyperplasia (PCH) presents with extreme proliferation of the epidermis with downgrowth into the dermis, which histologically mimics the features of squamous cell carcinoma. However, squamous cells usually are well differentiated, and atypicalities, such as individual cell keratinization, nuclear hyperplasia, and hyperchromasia, are minimal or absent. PCH has rarely been reported in LyP. Here, we showed that PCH associated with LyP may closely resemble squamous cell carcinoma, thereby giving rise to wrong diagnosis and treatment.

Superficial basal cell carcinoma (sBCC), a rare sub-type of basal cell carcinoma, can frequently occur in younger patients. This cancer type preferentially develops on the trunk. However, other subtypes of BCC can occur in the head and neck, probably secondary to sunlight exposure. Especially, sBCC on the scalp has been rarely-reported, accounting for 0.7~0.8% of all sBCC cases. We report a case of 71-year-old female with a large sBCC of the scalp, an unusual site of sBCC.

BACKGROUND: Narrowband UVB (NBUVB) is currently used to treat early mycosis fungoides (MF). There are a number of reports on the efficacy and safety of NBUVB in Caucasians, but little data is available for Asians. OBJECTIVE: This study was designed to evaluate the effectiveness and safety of NBUVB for early stage MF in Korean patients. METHODS: We enrolled 14 patients (12 men, 2 women; age range, 10~64 years) with clinically and histologically proven MF. Three patients were stage IA, and the others were stage IB. The patients received NBUVB phototherapy three times a week. The starting dose was 70% of the minimal erythema dose and was increased in 20 percent increments if the previous treatment did not cause erythema. Clinical response, total number of treatments, total cumulative dose, duration of remission and side effects were investigated. RESULTS: Eleven of 14 patients (78.6%) achieved complete remission within a mean of 15.36+/-5.71 weeks (range, 5~27 weeks), 31.0+/-7.4 treatments (range, 16~39 treatments) and a mean cumulative UVB dose of 31.31+/-12.16 J/cm2 (range, 11.4~46.8 J/cm2). Three of the 14 patients (21.4%) achieved a partial remission. After discontinuation of treatment, 6 of 11 patients (54.5%) with complete remission relapsed after a mean of 8.5+/-4.09 months. No serious adverse effects were observed except for hyperpigmentation (7/14, 50%). CONCLUSION: Our data suggest that NBUVB therapy is safe and effective for the treatment of early stage MF in Korean patients.

Pseudoxanthoma elasticum (PXE) is a heritable disorder of elastic tissue and it has many systemic manifestations. PXE is a systemic disorder that most markedly affects the elastic tissues in the skin, retina and blood vessels. Defects in the ABCC6 gene lead to calcification of elastic tissue. We herein report on two cases of pseudoxanthoma elasticum that presented with focal involvement on the skin of the neck without marked wrinkling.

Botryomycosis is a chronic, granulomatous and suppurative infection. The skin is the most frequently affected organ. The most common species is Staphylococcus aureus, followed by Pseudomonas aeruginosa. Clinically, the skin lesions most commonly affect the hands and feet and they can appear as nodules, ulcers, sinuses, fistulae and verrucous plaques. Histopathologic examination reveals grains with surrounding eosinophilic material and inflammatory cells. We report here on a case of botryomycosis at the excoriation site in a 90-year-old female patient with chronic eczema.

Cowden syndrome (CS) is a rare genodermatosis that is characterized by multiple hamartomatous tumors of an ectodermal, mesodermal and endodermal origin. CS is associated with an increased risk of malignancy and especially breast cancer, thyroid cancer, uterine cancer and renal cell carcinoma. The characteristic features of the disease are mucocutaneous findings, including multiple facial trichilemmomas, oral mucosal papillomatosis and acral keratoses. Multiple sclerotic fibroma is also known to be a clue to diagnose CS. We herein emphasize that multiple sclerotic fibromas of the skin are an important marker of CS, which may also be helpful for making an early diagnosis.
