ABSTRACT
Eccrine squamous syringometaplasia (ESS) is a histologically distinctive skin eruption occurring predominantly in acral or intertriginous areas presenting as erythematous macules, papules or patches. The etiology of ESS remains unclear, but it is usually reported in patients receiving chemotherapy for various malignant neoplasms. To date, only two cases of ESS associated with non-steroidal anti-inflammatory drugs (NSAIDs), which has distinctive clinical features and pathogenesis, have been reported in the literature. Herein, we report a rare and interesting case of ESS associated with pelubiprofen, a recently developed NSAID, which appeared after pelubiprofen therapy and resolved spontaneously after discontinuing the medication.
ABSTRACT
BACKGROUND: It has been suggested digital mucous cysts (DMCs) are associated with osteoarthritis and osteophytes in the elderly, and usually have a communicating pedicle with the joint. Surgical excision is a standard therapy with a high cure rate. OBJECTIVE: The purpose of this prospective study is to evaluate the features of DMCs via clinical, radiological and pathological examination and the efficacy of surgical excision of DMCs. METHODS: Between 2010 and 2014, 24 Korean patients were treated with the resection of the cyst and the pedicle. Preoperative X-ray and ultrasonography were performed to detect the presence of the osteophyte and the connection to the joint space. Postoperative patients' satisfaction score was assessed by the visual analogue scale (0~10). RESULTS: The osteophytes were found in 15.8%. In ultrasonographic findings, there were prominent flow signals between the cyst and the joint space in 13.6%. There were no serious postoperative complications, and recurrences were observed in 16.7%. Mean postoperative satisfaction score was 8.3. CONCLUSION: It seems that preoperative X-ray for osteophytes and ultrasonographic study for connection are not always helpful for the treatment of DMCs, and that the surgical excision with a pedicle ligation and electrocoagulation is an effective treatment modality.
ABSTRACT
BACKGROUND: Preoperative recognition of tumor plane is important to avoid surgical complications in surgeries involving the scalp. Ultrasonography is a useful diagnostic tool to detect the depth of tumor noninvasively. However, some findings are not always in accordance with the actual locations of lipomas, especially in the forehead. OBJECTS: To evaluate the accuracy of preoperative ultrasonographic findings for the location of lipomas in the forehead. MATERIALS AND METHODS: The study included 14 patients with lipomas in the forehead who all underwent preoperative ultrasonography and surgical excision of the lesions. The authors compared the diagnostic location of tumors by ultrasonography with the actual location in the surgical field. RESULTS: On ultrasonography, 10 of 14 cases were diagnosed as frontalis-associated lipomas. However, 13 cases were confirmed as frontalis-associated lipomas intraoperatively, and only 1 case as superficial lipoma, which did not correspond with the ultrasonographic finding. The ultrasonographic findings were accurate in 9 of 14 cases (64.3%). CONCLUSION: The accuracy of ultrasonography on the location of lipomas in the forehead is not as high as expected. Therefore, the surgeon must consider the possibility of deep lipoma even if a forehead lipoma is superficial in location on ultrasonography.
