The results already mentioned indicate that only here the peritoneum may become involved due to its proximity. The inflammatory changes depend less directly upon mechanical injuries than upon resulting infection; they may be confined to the mucous membrane or affect both it and the muscular tissue. In cases affecting the mucous membrane, a diphtheritic inflammation (endometritis diphtheritica) is observed, presenting similar characteristics to other mucous membranes with grayish colors and thick masses that can be removed. This condition must not be confused with remnants of decidua which are loosely adherent and easily removable.
The infiltration in the uterus first appears on prominent places such as the placental attachment, indicating an external source of infection. Changes within uterine walls vary according to their impact on blood vessels, lymphatics, or parenchyma. Blood vessel changes can be identified through perpendicular incisions revealing thrombi and clots varying in size from a plum to a walnut.
Lymphatic changes are characterized by clear yellow puriform masses filling the lymphatics without natural contents like blood. Parenchymal inflammation (metritis phlegmonosa or apostematosa) is marked by numerous pus collections of varying sizes, distinguishable from lymphatic sections due to their lack of smooth walls.
Total fatty degeneration of uterine walls can occur post-confinement and is often associated with general marasmus. Acute inflammatory affections are rare in non-puerperal uteri but may be easily diagnosed through purulent endometritis or phlegmonous inflammation within muscular tissue.
Chronic forms of inflammation are more common, characterized by slaty-colored mucous membranes due to previous small hemorrhages and fibrous induration converting the membrane into a smooth firm mass. Chronic metritis is marked by whitish-gray color and extreme hardness, often accompanied by an hour-glass form in uterine cavity.
Tuberculosis of the uterus is rare but can occur as disseminated miliary tuberculosis or cheesy degeneration (phthisis uterina). Both forms originate from mucous membrane changes. Carcinoma rarely originates in the body of the uterus but frequently affects the cervical portion, presenting either as a cauliflower excrescence or an ulcerative form.
Primary carcinoma produces thickened walls with grayish networks and white cancer juice upon sectioning. Common fibroids are the most frequent tumors, varying from pea-sized to head-sized, often soft and striated in appearance due to interwoven muscle and fibrous tissue bundles.

Tumors like fibroids are often multiple and may cause displacement of the uterus, necessitating careful monitoring and potential surgical intervention.
Key Takeaways
- Inflammatory changes in the uterus can be caused by infection rather than mechanical injury.
- Chronic inflammation is more common and characterized by fibrous induration of mucous membranes.
- Fibroids are the most frequent tumors, varying greatly in size and consistency.
Practical Tips
- Use perpendicular incisions to assess blood vessel conditions accurately.
- Monitor for slaty-colored mucous membranes indicative of chronic inflammation.
- Be aware that fibroid tumors can cause displacement of the uterus.
Warnings & Risks
- Do not confuse diphtheritic inflammation with remnants of decidua.
- Chronic metritis often presents an hour-glass form in uterine cavity, indicating severe condition.
- Primary carcinoma produces thickened walls and requires immediate medical attention.
Modern Application
While the detailed anatomical descriptions remain valuable for understanding pathological conditions, modern diagnostic techniques such as MRI and CT scans provide more accurate and non-invasive methods. However, historical knowledge is crucial for recognizing symptoms and guiding initial treatment decisions.
Frequently Asked Questions
Q: What are the key differences between diphtheritic inflammation and remnants of decidua?
Diphtheritic inflammation (endometritis diphtheritica) presents with thick gray masses that can be removed from a surface with a gray, grayish-yellow or grayish-white color. Remnants of decidua are loosely adherent to the surface and easily removable by water.
Q: How does chronic inflammation manifest in uterine walls?
Chronic inflammation is characterized by fibrous induration converting the mucous membrane into a smooth, firm mass that cuts with difficulty. The walls may also become whitish-gray and extremely hard due to fibrous degeneration.
Q: What are the diagnostic features of primary carcinoma in the uterus?
Primary carcinoma produces thickened uterine walls with grayish networks from which white or yellowish-white cancer juice can be pressed out. The surface of the cavity may remain intact without ulceration.
