Assessment of the Rectum and Anus

Assessment of the Rectum and Anus

Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Gastroenterology
Oncology
Pathology

Background:

Anorectal melanoma is an uncommon and lethal malignancy.
It presents diagnostic challenges and has a poor prognosis.
Distinguishing it from cutaneous melanoma is crucial.

Purpose of the Study:

To review the epidemiologic, clinicopathologic, and molecular features of anorectal melanoma.
To compare anorectal melanoma with its cutaneous counterpart.
To discuss surgical outcomes, survival predictors, and adjuvant therapies.

Main Methods:

Literature review and synthesis of existing data.
Analysis of epidemiologic, clinicopathologic, and molecular characteristics.
Evaluation of surgical resection outcomes and therapeutic strategies.

Main Results:

Anorectal melanoma exhibits unique features compared to cutaneous melanoma.
Surgical management remains controversial with variable outcomes.
KIT oncogene activation identified in a subset of patients.

Conclusions:

Anorectal melanoma requires distinct diagnostic and management approaches.
Targeted molecular therapies, potentially including KIT inhibitors, show promise.
Further research is needed to improve survival rates for this rare cancer.
