Proliferative fasciitis in the abdominal region
Skinmed
|June 18, 2014
Summary
A 30-year-old man presented with painful abdominal masses. Histopathology revealed unusual spindle-shaped fibroblast and gangliocyte-like cells, suggesting a rare soft tissue neoplasm.
Area of Science:
- Dermatology
- Pathology
- Oncology
Background:
- Soft tissue neoplasms can present as subcutaneous nodules.
- Abdominal masses require thorough histopathological evaluation for accurate diagnosis.
Observation:
- A 30-year-old man presented with a 2-year history of progressively painful abdominal masses.
- Physical examination revealed three firm, irregular, movable subcutaneous nodules, one of which was ulcerated.
- Histopathology demonstrated spindle-shaped fibroblast cells and gangliocyte-like giant cells in the hypodermis.
Findings:
- Immunohistochemical staining was negative for anti-S100 protein and anti-smooth muscle actin in the neoplastic cells.
- The cellular morphology and immunohistochemical profile suggest a rare type of soft tissue tumor.
Implications:
- Accurate diagnosis of rare soft tissue tumors is crucial for appropriate patient management.
- This case highlights the importance of comprehensive histopathological and immunohistochemical analysis in diagnosing unusual cutaneous lesions.

Appendicitis-I: Introduction
4.4K
The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...

Layers of Connective Tissue Proper

Fascia, a thin layer of fibrous connective tissue, is distributed throughout the body. It demarcates and forms a supportive covering over skeletal muscles, bones, blood vessels, and organs. There are three main types of facia— superficial fascia, deep fascia, and subserous fascia. These are all present at different depths in the body. Fascia reduces the friction and permits muscles, joints, and organs to easily slide against each other, facilitating movement of the body and preventing...

Abdominal Regions and Quadrants
17.2K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Appendicitis
28
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...

Muscles of the Abdomen
4.6K
The abdominal wall encircles the abdominal cavity, providing flexible protection and shielding the internal organs from harm. It is bordered at the top by the xiphoid process and costal margins, at the back by the vertebral column, and at the bottom by the pelvic bones and inguinal ligament. The abdominal wall is divided into two regions — the anterolateral and posterior regions.
Anterolateral Region
The anterolateral region comprises five paired muscles classified into the lateral and...

Veins of the Abdomen and Pelvis

The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
