Three Weird Signs of Colon Cancer Found on the Skin
Colon cancer is a prevalent form of cancer that affects the large intestine and rectum. While abdominal pain, stool caliber changes, and bowel habit changes are commonly associated with colon cancer, there are rare skin findings that can also serve as indicators of an underlying colon cancer. This article aims to shed light on these three peculiar skin signs that may indicate the presence of colon cancer. It is important to note that these findings are relatively rare but warrant attention if observed in patients.
Introduction (#introduction)
Colon cancer, also known as colorectal carcinoma, ranks as the third to fourth most common type of cancer globally. Understanding the signs and symptoms, along with the risk factors associated with this disease, is crucial for early detection and effective treatment.
Understanding Colon Cancer (#understanding-colon-cancer)
Colon cancer primarily affects the large intestine and rectum. It can manifest in various segments, including the ascending colon, transverse colon, descending colon, or rectum. The exact causes of colon cancer remain unclear, but certain factors increase its risk. These include older age, a low fiber diet over an extended period, a family history of colon cancer, and inflammatory bowel diseases such as Crohn's disease and ulcerative colitis.
Risk Factors for Colon Cancer (#risk-factors-for-colon-cancer)
Several risk factors can increase the likelihood of developing colon cancer. These factors include:
- Advanced age
- Low fiber diet
- Family history of colon cancer
- Inflammatory bowel disease (Crohn's disease or ulcerative colitis)
Exploring these risk factors in detail can provide a better understanding of the disease and its prevalence.
Common Signs and Symptoms (#common-signs-and-symptoms)
Colon cancer presents a range of signs and symptoms that can help in its identification. The following are the most frequently observed symptoms:
Abdominal Pain (#abdominal-pain)
Abdominal pain is the most common symptom associated with colon cancer. This pain may vary in intensity and persistence, and its presence should not be ignored.
Stool Caliber Changes (#stool-caliber-changes)
Changes in stool caliber, specifically thinning or pencil-shaped stools, can indicate the presence of a large tumor obstructing the colon. This transformation can result in difficulty during bowel movements.
Bowel Habit Changes (#bowel-habit-changes)
Colon cancer can lead to alterations in bowel habits, such as frequent episodes of diarrhea or constipation. Some individuals may experience alternating bouts of both.
Rare Skin Findings as Indicators of Colon Cancer (#rare-skin-findings-as-indicators-of-colon-cancer)
While uncommon, certain dermatological findings can serve as indicators of an underlying colon cancer. These findings, known as paraneoplastic syndromes, are specifically linked to colon cancer as well as other gastrointestinal malignancies. The three peculiar skin findings to watch out for are:
Lesser Trella Sign (#lesser-trella-sign)
The Lesser Trella sign refers to the sudden onset of numerous seborrheic keratosis lesions. Seborrheic keratosis is a commonly found benign condition in older individuals. However, the sudden appearance of many of these lesions can be a rare indicator of an underlying colon cancer. It is worth noting that these lesions are often itchy and experience a rapid increase in size and number.
Malignant Acanthosis Nigricans (#malignant-acanthosis-nigricans)
Malignant acanthosis nigricans is characterized by thickened and hyperpigmented skin lesions, often displaying a velvety appearance. While this condition is more commonly associated with obesity and type 2 diabetes, it can, in rare cases, be linked to colorectal adenocarcinoma. Patients may simultaneously present with both malignant acanthosis nigricans and the Lesser Trella sign.
Hypertrichosis Lenogenosa (#hypertrichosis-lenogenosa)
Hypertrichosis lenogenosa involves the abnormal growth of fetal or lanugo hair. While this condition is typically associated with metabolic and endocrine conditions, in rare instances, it may also develop in patients with colorectal cancer or other malignancies. However, it is essential to consider other underlying causes before linking hypertrichosis lenogenosa solely to colon cancer.
Other Types of Cancer Associated with Skin Findings (#other-types-of-cancer-associated-with-skin-findings)
Though rare, these dermatological findings might not exclusively indicate colon cancer. They can also be associated with other gastrointestinal malignancies, such as gastric cancer. In addition to colorectal adenocarcinoma, skin findings can also indicate the presence of other cancers like lung cancer and breast cancer.
Conclusion (#conclusion)
While colon cancer typically presents with common symptoms like abdominal pain and changes in bowel habits, certain rare skin findings can potentially aid in early detection. The Lesser Trella Sign, malignant acanthosis nigricans, and hypertrichosis lenogenosa should not be overlooked as potential indicators of underlying colon cancer. Timely recognition of these skin findings, in combination with other clinical symptoms, can contribute to prompt diagnosis and intervention.

FAQ (#faq)
Q: Are these skin findings common in patients with colon cancer?
A: No, these skin findings are relatively rare but can serve as important indicators when identified.
Q: Can these skin findings occur in individuals without colon cancer?
A: Yes, these skin findings can also be associated with other conditions and cancers, so it is important to consider various factors before concluding a link to colon cancer.
Q: Do all patients with colon cancer exhibit these skin findings?
A: No, these skin findings are not present in all cases of colon cancer. The majority of patients with colon cancer may not display such dermatological signs.
Q: Can these skin findings be treated independently of colon cancer?
A: Treatment of these skin findings is primarily focused on addressing the underlying cause, such as colon cancer or other associated conditions. Addressing the root cause is essential for effective management.
Q: Are there any additional tests required to confirm colon cancer if these skin findings are present?
A: The presence of these skin findings should prompt medical professionals to conduct further investigations, including imaging tests, colonoscopy, and biopsies, to confirm the diagnosis of colon cancer.
