Autism spectrum disorder involves challenges in social communication and restricted, repetitive behaviors. Historically, males have received autism diagnoses at comparatively high rates, prompting an underrepresentation of females in research and an incomplete understanding of sex-specific symptom presentations and comorbidities. This review examines sex differences in the prevalence of common comorbidities of autism to inform tailored clinical practices. These conditions include attention deficit hyperactivity disorder, anxiety disorders, conduct disorder, depression, epilepsy, intellectual disability, and tic disorders. Attention deficit hyperactivity disorder is prevalent in both sexes; however, females may more frequently exhibit the inattentive subtype. Anxiety disorders display inconsistent sex differences, while conduct disorder more frequently impacts males. Depression becomes more common with age; some studies indicate more pronounced symptoms in adolescent girls, while others suggest greater severity in males. Epilepsy is more prevalent in females, especially those with intellectual disabilities. Despite displaying a male predominance, intellectual disability may exacerbate the severity of autism to a greater degree in females. No clear sex differences have been found regarding tic disorders. Overall, contributors to sex-based differences include biases stemming from male-centric diagnostic tools, compensatory behaviors like camouflaging in females, genetic and neurobiological differences, and the developmental trajectories of comorbidities. Recognizing these factors is crucial for developing sensitive diagnostics and sex-specific interventions. Inconsistencies in the literature highlight the need for longitudinal studies with large, diverse samples to investigate autism comorbidities across the lifespan. Understanding sex differences could facilitate earlier identification, improved care, and personalized interventions, thus enhancing quality of life for individuals with autism.

6.Genetics of Autism Spectrum Disorder: Current Status and Possible Clinical Applications.
Experimental Neurobiology 2015;24(4):257-272
Autism spectrum disorder (ASD) is one of the most complex behavioral disorders with a strong genetic influence. The objectives of this article are to review the current status of genetic research in ASD, and to provide information regarding the potential candidate genes, mutations, and genetic loci possibly related to pathogenesis in ASD. Investigations on monogenic causes of ASD, candidate genes among common variants, rare de novo mutations, and copy number variations are reviewed. The current possible clinical applications of the genetic knowledge and their future possibilities are highlighted.

7.Early Detection and Intervention of Autism Spectrum Disorder.
Hanyang Medical Reviews 2016;36(1):4-10
Autism spectrum disorder (ASD) is a neurodevelopmental disorder typically identified in early toddlerhood. Both retrospective and prospective follow up studies of high risk infants reveal early risk signs of ASD at 12-24 months of age. The most frequently replicated early signs of ASD are atypical visual tracking and coordination, lack of social reciprocity, abnormal social communication and unusual patterns of manipulating objects, atypical sensory exploration, expressed as uncoordinated eye contact, unresponsiveness to naming, lack of social smile, delayed development of nonverbal communication and joint attention, less sharing interest, and unusually repetitive use of objects. Early intervention, before 2 years of age, appears to change the underlying developmental trajectories of the brain in individuals with ASD. In this review, the early risk signs of ASD in infancy and toddlerhood, along with early intervention and their implications, are discussed.

We recently experienced an atypical chondroid lesion metastatic to the lung. Examined under the microscope, the excised nodules displayed abundant amounts of chondroid tissue and necrosis with dystrophic calcification. The calcification had a characteristic "chicken wire" pattern. The chondroblasts contained one or two round to oval, focally indented nuclei with inconspicuous nucleoli. Although some enlarged nuclei with mild to moderate pleomorphism were present, significant nuclear atypia was lacking. Mitotic figures were scarce (1/10 high power field). Scattered multinucleated osteoclast-type giant cells were observed among the chondroblasts. Thus, the possibility of chondroblastoma was considered first. Metastasis of histologically benign chondroblastoma is a rare event, but well documented. The pulmonary metastatic nodules were described as ceasing to grow in some cases; and a significant number of patients were free of tumors following removal of the metastatic nodules. These findings suggest that the metastasis may represent a simple transport phenomenon. However, there are, as yet, no histologic parameters that help determine whether these metastases are to cease their growth or will progress to kill the host.

Primary mesenchymal neoplasm of the adrenal gland is very rare. Recently we experienced a case of leiomyosarcoma of the adrenal gland in a 47-year-old female patient. The resected adrenal gland showed a large lobulated mass, which replaced the entire gland. The cut surface was firm and whitish gray with foci that showed hemorrhage and necrosis. Histologically, the tumor was composed of intersecting fascicles of pleomorphic spindle cells with numerous giant cells and mitotic figures. Some of the tumor cells showed elongated nuclei. Immunohistochemical studies were strongly positive for vimentin and smooth muscle actin. Cytokeratin, desmin, alpha-1-antitrypsin and lysozyme were all negative. To the best of our knowledge, this is the first case reported in Korea.
