Proliferative myositis is a rare, benign, probably pseudosarcomatous fibroblastic proliferation that typically presents as a rapidly growing soft tissue mass. Its relative rarity, fast growth rate, and unique histopathologic findings may lead to misdiagnosis as a malignant lesion and unnecessary radical surgical excision. A 57-year-old female presented with a non-tender, well-defined, indurated, solitary, hard papule on the median sulcus of the tongue for 2 weeks. Histologic examination revealed numerous fibroblastic or myofibroblastic spindle cells and large ganglion-like cells infiltrating between and around the muscle fascicles. Immunohistochemical staining showed positivity for vimentin, smooth muscle actin, and CD68 and negativity for S-100. Based on these characteristic clinical findings and histopathologic features, the patient was diagnosed with proliferative myositis. Here, we report a rare case of proliferative myositis on the tongue and recommend considering proliferative myositis in the differential diagnosis when a physician encounters a rapidly grown soft tissue mass.

SAPHO (synovitis, acne, pustulosis, hyperostosis, and osteitis) syndrome includes a variety of inflammatory bone disorders associated with dermatologic pathology. A 57-year-old female presented with pustulosis on both hands that had persisted for several months. She also had lower back pain without trauma history. On physical examination, tenderness on her lower back and left anterior chest wall pain were found, and claudication was observed. Radiological studies including computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET)-CT showed endplate lytic changes in her spine, a focal hypermetabolic lesion in a left rib, and costochondral junction. These findings raised doubt on the presence of metastatic bone lesions, and there was no indication for primary cancer after a complete medical checkup. Palmoplantar pustulosis was well controlled by treatment with acitretin. The osteitis associated with SAPHO syndrome usually presents as osteosclerosis, while reports on osteolytic lesions are rare. We report herein a rare case of SAPHO syndrome associated with bone lesions resembling bone metastasis.

Although hair loss in Cronkhite-Canada syndrome (CCS) developed frequently, its exact mechanism has not been elucidated. Thus, we attempted to investigate the histopathologic features of hair loss with scalp biopsy in one case of CSS. The patient complained of persistent diarrhea and diffuse hair loss of the scalp 1 month prior to the hospital visit. CCS has been already diagnosed through colonoscopy and medical examination. Scalp biopsy was performed to evaluate hair loss of the patient, and pathologic examination showed increased telogen hairs (anagen to telogen is 7:8) without specific dermal inflammation and miniaturization of hair follicles. The patient was treated with topical and systemic steroids, and hair loss has almost completely recovered in 5 months. In this case, we investigated the clinical and pathological features of hair loss through scalp biopsy in one case of CCS and reported them with a review of the literature.

BACKGROUND: Balneotherapy, although not a well-established treatment, has been used for dermatologic diseases from ancient to modern times. However, there is little knowledge regarding the current awareness of balneotherapy in dermatologic patients and dermatologists. OBJECTIVE: To understand the current situation of balneotherapy, we first evaluated the utilization and awareness of balneotherapy among dermatology outpatients and dermatologists. METHODS: A written questionnaires were completed by 183 outpatients who visited the Department of Dermatology at a University Hospital. Online questionnaires were completed by 37 dermatologists. RESULTS: Only a small percentage of the outpatients used thermal springs/spas for therapeutic purposes. On the contrary, 93% of them used it for leisure and rest. Most outpatients thought the cleanliness of water is the most important factor in thermal springs/spas. Both outpatients (81%) and dermatologists (81%) regarded balneotherapy as a medically unestablished folk remedy. Though regarded as a folk remedy, almost all outpatients (98%) thought that balneotherapy helps improve general health problems, such as fatigue and skin diseases, or conditions related to blood circulation, pain, and joint/muscle. Participants thought that dermatology and rehabilitation medicine can be connected to balneotherapy. Although they thought that balneotherapy can improve general health, most dermatologists (70%) mentioned that it is difficult to judge the efficacy of balneotherapy owing to the lack of sufficient evidence. CONCLUSION: Although not yet considered as a confirmative therapeutic modality owing to the lack of medical verification, there is positive recognition and outlook for the effect of balneotherapy in Korea. To offer precise information to patients, more attention from dermatologists would be needed to confirm its actual efficacy.
