Notalgia paresthetica refers to an isolated mononeuropathy involving chronic localized itch or paresthesia most often at the skin of the scapula or surrounding regions. There are no specific skin manifestations except those arising from chronic scratching and rubbing. The specific etiology remains unknown; however, it has been theorized that the neuropathic itch is caused by sensory nerve entrapment involving the posterior rami of the T2 to T6 nerve root. The entrapment is due to degenerative changes in the vertebrae. We report here a particular case of notalgia paresthetica in a 55-year-old woman. The patient visited our hospital for tingling pain around the left inferior angle of the scapula. Pruritus was first reported seven years ago with tingling pain developing only four months ago. There were no specific skin lesions observed except for excoriation and vague hyperpigmentation. A skin biopsy revealed only epidermal thinning with pigmentary incontinence. The patient was treated with 600 mg of gabapentin daily as well as capsaicin cream. The response was deemed unsatisfactory.

PURPOSE: Behcet's disease (BD) is rarely reported to be associated with malignancies in the literature. However, the frequency of cancer in BD patients remains unknown. This study evaluated cancer morbidity in BD patients compared with that in the general population of Korea. MATERIALS AND METHODS: A retrospective chart review was performed on 506 patients visiting our hospital from 1994 to 2011 for BD. We analyzed the standardized morbidity rate (SMR), which is the ratio of observed to expected malignancies. Furthermore, we reviewed cases of solid cancer in BD patients in the literature. RESULTS: Of the 506 patients with BD, 11 (2.17%) developed cancer. We found a variety of solid cancers without predominance and no hematologic malignancies. The total number of cancers observed was less than expected, which was determined from the statistical data of the National Cancer Information Center of Korea, with an SMR of 0.023 (95% confidence interval, 0.012-0.039). CONCLUSION: BD may be associated with a lower cancer-related morbidity compared with the general population of Korea.

BACKGROUND: Recently, photodynamic therapy (PDT) has been shown to be an effective first-line treatment for actinic keratosis (AK). However, a major limitation of PDT is the long incubation time required to allow penetration of the photosensitizer. OBJECTIVE: The aim of this study was to assess if pretreatment with an ablative carbon dioxide (CO2) fractional laser can reduce the incubation time of the photosensitizer. METHODS: Initially, 29 patients with a total of 34 AK lesions were treated with an ablative CO2 fractional laser at Ajou University Hospital between January and December 2010. Immediately after the laser treatment, topical 20% 5-aminolevulinic acid or methyl-aminolevulinate was applied to the AK lesions and incubated for 70 to 90 minutes. Then, the treated areas were illuminated with a red light source. Improvement was clinically or histologically assessed eight weeks after the treatment. RESULTS: In spite of the short incubation time, 24 lesions (70.6%) showed a complete response (CR) within three sessions of PDT (10 lesions a clinical CR and 14 lesions a clinical/histological CR). There were no significant side effects associated with the combination of ablative CO2 fractional laser and PDT. CONCLUSION: Ablative CO2 fractional laser may be considered an additional treatment option for reducing the incubation time of the photosensitizer in PDT.

BACKGROUND: Eccrine angiomatous hamartoma (EAH) is a rare benign nodular lesion characterized by the proliferation of eccrine and vascular structures, generally capillaries, in the middle and deep dermis. It may be congenital or appear later in childhood, but rarely arises in adulthood. OBJECTIVE: To investigate the clinicopathologic features of EAH in Korean patients. METHODS: Ten cases of EAH diagnosed at Ajou University Hospital and Gangnam Severance Hospital in Korea from 2007 to 2010 were retrospectively reviewed. RESULTS: The age range of patients was between 5 and 66 years with an equal number of male and female patients. Apart from two congenital cases, the onset was late, ranging from 6 months to 65 years of age. All lesions were solitary and located on the distal extremities. Nine cases appeared as a yellow-brown nodule or plaque resembling a callus. Neither hyperhidrosis nor hypertrichosis was documented. Apart from the typical histological findings of EAH, prominent mucin deposition, fat component and nerve infiltration were observed. CONCLUSION: This is one of the largest single case series of EAH in the literature. Clinically, resemblance to callosities and the frequent occurrence in the adulthood were the unique features in our series.
