Rationale:Apocrine carcinoma is a rare malignant sweat gland tumor that has been reported in approximately 200 cases. This tumor usually occurs in the axilla, but in rare cases, it can also develop in the scalp. In the present work, we report 2 cases of cutaneous apocrine carcinoma of the scalp.Patient concerns:Two men visited our outpatient clinic with recurrence of tumor after undergoing surgery for scalp tumor at another hospital.Diagnoses:Brain magnetic resonance imaging of a 56-year old man showed the presence of a 5.0 × 4.5 × 4.4 cm scalp mass in the right parietal region, invading the skull and dura mater and a 2.2 × 2.0 × 0.7 cm bony mass without any skin lesions right next to the scalp mass. Neck magnetic resonance imaging of a 76-year-old man revealed the presence of a well-defined oval mass in the subcutaneous layer of the left occipital scalp and 2 enlarged lymph nodes in the left neck. Definite diagnoses were made postoperatively. The patients were diagnosed with cutaneous apocrine carcinoma. The diagnosis was confirmed through histopathological and immunohistochemical staining tests.Interventions:The tumors were removed with a wide safety margin and reconstructive surgery was performed.Outcomes:Additional radiotherapy or chemotherapy was performed. Follow-up more than 6 months revealed no recurrence or metastasis.Lessons:If accurate diagnosis and treatment had taken place at the initial stages of the primary cutaneous apocrine carcinoma, it would have been possible to prevent recurrence and intracranial invasion. As recurrent primary cutaneous apocrine carcinoma can become aggressive and difficult to treat, even a small mass on the scalp must be evaluated carefully and treated properly.

BACKGROUND The most common causes of compartment syndrome in the lower extremities include lower limb fractures, trauma-induced crushing injuries, severe burns, and non-traumatic factors. However, there have been no reports of compartment syndrome secondary to toxic inhalation. CASE SUMMARY A 59-year-old man, who lost consciousness after applying polyurethane-based paint on a water tank, was brought to the emergency room. The initial blood test showed apparent rhabdomyolysis. One day later, pain and swelling in both legs were observed, and the physical examination confirmed the presence of compartment syndrome. Double-incision fasciotomy was performed on both legs. Frequent dressings and negative pressure wound treatment were done on both legs, and skin grafting was performed after healthy granulation tissue had been identified. No other complications were observed after treatment. However, symptoms of peroneal neuropathy, particularly limited ankle dorsiflexion and reduced sensation on the lower extremities, were observed. CONCLUSION Workers using polyurethane agents should wear gas masks and be evaluated for compartment syndrome and rhabdomyolysis secondary to toxic inhalation.

Background and ObjectivesZZVarious surgical techniques have been tried to relieve nasal obstruction in patients who have hypertrophic inferior turbinate. Recently, coblators and microdebriders are the favored surgical procedure. This study is aimed at evaluating the long term efficacy of posterior resection of inferior turbinate performed on patients for whom the previous inferior turbinate surgery had not relieved the symptoms of nasal obstruction. Subjects and MethodZZWe selected 27 patients who have had previous inferior turbinate surgery, but were not relieved of the symptom for nasal obstruction. Under local or general anesthesia, hypertrophied posterior part of inferior turbinate was removed. The symptom changes of nasal obstruction and patients satisfaction were checked pre and postoperatively at 1, 2, 3, 6, 12 month by Visual Analogue Scale (VAS) score. The minimal cross-sectional area of second notch and volume of nasal cavity were measured at 1, 2, 3, 6, 12 month after operation. ResultsZZThere were significant improvement in the VAS score of nasal obstruction and patient satisfaction after the operation. The minimal cross-sectional area of second notch did not change significantly after surgery, but the nasal cavity volume was significantly improved after surgery. ConclusionZZThis study suggests that posterior resection of inferior turbinate is an effective surgical procedure for patients who have hypertrophic inferior turbinate especially on the posterior part.
