Summary
This study confirms a rare perianal atypical leiomyoma using clinical, MRI, and immunohistochemistry. Complete surgical resection and regular follow-up are crucial for managing this benign tumor to prevent recurrence.
Area of Science:
- Gastroenterology and Surgical Oncology
- Pathology and Diagnostic Imaging
Background:
- Perianal atypical leiomyoma is a rare perianal tumor with limited case reports.
- Distinguishing benign atypical leiomyoma from potentially malignant smooth muscle tumors can be challenging.
Observation:
- A 28-year-old female presented with a perianal mass of over four years duration.
- Magnetic resonance imaging (MRI) revealed a 4.1cm x 5.2cm x 4.9cm round mass on the left side of the anus and vagina.
Findings:
- The diagnosis of perianal atypical leiomyoma was confirmed through clinical presentation, MRI, and immunohistochemistry.
- Surgical resection of the anal peripheral mass was successfully performed under lumbar anesthesia.
Implications:
- Complete surgical resection is essential for perianal atypical leiomyoma to prevent recurrence.
- Regular postoperative follow-up is recommended due to the potential for malignant changes or recurrence.

01:21Antipsychotic Drugs: Typical and Atypical Agents
933
Antipsychotic drugs are classified into first-generation (typical) drugs including phenothiazines; and second-generation (atypical) drugs. Chlorpromazine hydrochloride (Thorazine), a phenothiazine derivative, broadly impacts the central, autonomic, and endocrine systems. This drug, along with typical agents like haloperidol (Haldol), primarily works by antagonizing D2 receptors, thus reducing dopaminergic neurotransmission. However, typical antipsychotics can cause side effects such as sedation...

01:24Data Reporting and Recording
5.5K
Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...

02:11Reporter Genes
13.4K
Reporter genes are a type of protein-coding gene that are often tagged to a gene of interest. Once inside a target cell, reporter genes usually produce visually identifiable characteristics like fluorescence and luminescence when expressed along with the gene of interest. Thus, reporter genes “report” the presence or absence of genes of interest in an organism, determine the gene expression pattern, or track the physical location of a DNA segment or protein in the cell.
