    Skin and nail lesions in the feet and toe deformities often occur during childhood; however, medical and educational institutions have performed only a few large-scale investigations regarding foot and toe deformities. To reveal the abnormal findings, symptoms, and lifestyle habits of elementary school students, a web questionnaire was administered to the students and parents in some elementary schools, collaborating with the Sokuiku Laboratory and Japan Organization of Clinical Dermatologists. Overall, 575 responses were obtained. Approximately 20% of the participants answered, “there are toe deformities” the percentage increased in the upper grades. “Parents do nail clippers” decreased in middle and upper grades. Of the participants, >50% answered, “they do not have enough time to exercise.” Compared to the previous survey results, this present survey results showed a lower rate of toe deformities and motor function abnormalities. Because abnormal findings may not be found at home, regular measurements at school are necessary for accurate investigation. It is well known that a lack of exercise in school children leads to poor motor function development. Considering that problems with foot deformities, lower limb function, and toenails are linked to declined lower limb function, for healthy growth and development in early childhood and prevention of locomotive syndrome in middle and old age, it is recommended that, besides exercise instruction, school health education should include foot education, such as instructions on foot care and shoes, starting in the early elementary school grades, and foot measurements should be added to musculoskeletal health examinations.

    A 65-year-old man was undergoing thorough examination for his pericardial pain and was found to have a tumor in the glans, numerous lymphadenopathy, and abnormal lung shadows. Since these lesions showed fluorine-18-deoxyglucose (FDG) uptake by positron emission tomography (PET), he had been suspected to have penile cancer and multiple metastasis. He was referred to our department for histological examination of his penile tumor. A physical examination showed that a red nodule with erosive surface on the glans penis. A histopathological examination showed epidermal hyperplasia and dense cellular infiltration with numerous plasma cells in the dermis. The rapid plasma reagin(RPR) and Treponema pallidum hemagglutination test revealed(TPHA) 706.5 R.U. and TPHA 20480-fold, respectively. Taken these together, a diagnosis of secondary syphilis was made. After oral administration of amoxicillin was started, the penile nodule, the lymph node swelling, and lung abnormal shadows were subsided. Dermatologists should be aware that the clinical presentation of secondary syphilis may resemble penile cancer, and that multiple lymphadenopathy and pulmonary lesions may occur, and that these lesions can show FDG uptake by FDG-PET.

    In general, basal cell carcinoma (BCC) presents as a dark brown, wax-like, shiny nodule. BCC without pigmentation is called non-pigmented BCC. Differentiating nonpigmented BCC from eczema or Bowen's disease using their appearance and gross examination is challenging. Here, we report a case of a 58-year-old Caucasian male patient with nonpigmented BCC, which was suspected using dermoscopy at the initial examination. He presented to our hospital 2 years prior with erythema on his back during a follow-up visit for evaluation of solar keratosis on the dorsal surface of his left hand, which was treated using topical imiquimod cream. Dermoscopic imaging revealed erythematous and well-defined erythema on the back, with internal ulceration and short fine vessels around the erythema. White linear structures, such as shiny white areas and yellow-white clods, were determined using polarized and unpolarized light. Non-pigmented BCC was diagnosed, and resection was performed with a 3 mm-margin. Since then, there has been no recurrence. Findings unrelated to pigmentation, such as short fine vessels, ulceration, shiny white areas, and large and small yellow-white globules, are helpful in the diagnosis of non-pigmented BCC.

    Ingrown toenails and pincer nails are commonly encountered in dermatological practice. As no standardized treatment systems exist, especially among clinics, several treatments are currently provided according to the technical levels of each medical institution. Since the opening of our clinic in 1997, we have continuously used our ingenuity to provide short-lasting, low-cost, highly effective, and painless treatments. This study analyzed a total of 306 new patients (101 men and 205 women) with ingrown toenails or pincer nails, who visited our clinic in 2022. Based on the history of previous treatments and the age at onset, it was considered appropriate to classify ingrown toenails into the following four types: type 1 (ingrown lateral edges of the nail plate; n = 34), type 1G (type 1 with granulation tissue; n = 36), type 2 (ingrown lateral tips of the nail plate; n = 76), and type 2G (type 2 with granulation tissue; n = 18). Pincer nail was classified as type 3 (n = 135) and type 3G (pincer nail with granulation tissue; n = 6). There was 1 case classified as ‘other.’ Statistical and clinical analyses were performed using this classification. The mean age of the patients was 27.8 years in type 1 (including type 1G), 41.0 years in type 2 (including type 2G), and 62.6 years in type 3 (including type 3G). At our clinic, all these types are treated with conservative therapy with carbon dioxide laser as the first-line treatment. The use of laser to bend an ingrown or pincer nail allows us to reduce the treatment duration and costs. Our cases have been reported in this article.

    A 7X-year-old man was discovered unconscious while sitting in a sauna, without significant medical history. He was diagnosed with heat stroke-associated unconsciousness, convulsions, and epidermal burns on 71% of his body surface area, with superficial dermal burns on 11%. Although his general condition improved on day 14 of hospitalization ceased on day 14 of hospitalization, gangrene in the toes were gradually progressing. Amputation of the right 1st and 2nd toes, and all the left toes was performed. Also, bilateral patellar periosteal suturing followed by artificial dermal skin grafting, and negative pressure closure therapy for the ulcer on the right thigh were performed. The ulcer on the right patella was reconstructed using partial-thickness skin grafting. The cause of the amputation of the toes was likely the prolonged loss of consciousness due to full thickness burns to the nose and ears, attributable to prolonged contact with a hot sauna floor bearing his weight on both feet. And, this supportive sitting position likely contributed to ischemic complications. This case highlights the need to raise awareness about potential skin disorders arising in special environment of saunas.

    A 25-year-old woman repetitively manifested subcutaneous painful indurated nodules on the sites of insulin injection. She had type 1 diabetes mellitus and was treated at the Department of Endocrinology and Metabolism. Her symptom was suspected as amyloidosis, and she was referred to our department for further examination. She presented 19 painful subcutaneous indurated nodules of 2 to 5 cm in diameter on the abdomen, which was suspected as insulin ball firstly. However, the subcutaneous nodules also occurred at the site of only one injection .Therefore, suspecting insulin allergy, drug lymphocyte stimulation test was perfomed. The test revealed positivity for insulin glargine U 300 and insulin degludec. The patient was diagnosed with insulin allergy. She was treated with topical betamethasone butyrate propionate. Alteration of the fast-acting insulin from lispro-aabc to aspart and the long-acting insulin from glargine U300 to degludec reduced the number of indurated nodules decreased and improved pain.
