ABSTRACT
Anaplastic large cell lymphoma (ALCLs) are a group CD30-positive mature T-cell lymphomas, an uncommon subtype of non-Hodgkin lymphomas, characterized by diverse clinical and genetic features. Among the types of ALCL, anaplastic lymphoma kinase (ALK)-negative ALCL, though typically involves the lymph nodes, can infrequently invade other tissues. When soft tissue involvement occurs, it may mimic the clinical presentation of infectious diseases, leading to potential misdiagnosis. Therefore, a histological examination is necessary to differentiate between ALK-negative ALCL and similar phenotypes associated with infectious conditions. This paper reports a case of ALCL, initially misdiagnosed as an infection.
ABSTRACT
Headaches and sleep problems are burdensome in daily life. They can co-occur and aggravate each other. The prevalence of sleep disorders is high in chronic headache and migraine patients, suggesting a close clinical relationship between these conditions. Structures from the brainstem to the cerebral cortex are related to sleep and headache modulation. In addition, various neurochemicals are related to and overlapped in the modulation of sleep and headache. In this paper, we briefly review the association between migraine and sleep disorders, including insomnia, sleep-related breathing disorders, central disorders of hypersomnolence, circadian rhythm sleep-wake disorder, parasomnias, and sleep-related movement disorders.

ABSTRACT
Surfer's myelopathy is a rare nontraumatic spinal cord disorder associated with surfing. This study reports three patients with surfer's myelopathy. All patients were young males who were previously healthy and first-time surfers at the onset of their symptoms. They developed the symptoms while surfing or shortly thereafter, presenting with lower back pain followed by an acute myelopathy. Spine magnetic resonance imaging showed T2 hyperintense cord lesion. Since the number of surfers is increasing in Korea, awareness of surfer's myelopathy is necessary for early recognition and proper management.
