The spleen is an important lymphatic organ that is involved in filtration of the blood by discarding old and damaged red blood cells as well as maintaining platelet levels. The spleen is a lymphatic organ, which means it is largely involved in the immune system and immune responses. When the spleen becomes enlarged, it is a strong sign of infection somewhere in the body and can be caused by inflammatory conditions such as rheumatoid arthritis. The increased need for production assistance of white blood cells to affected areas causes hyperfunction of the spleen. This increase in defense activities ultimately causes hypertrophy of the spleen, leading to splenomegaly. The spleen is found in the left upper quadrant (LUQ) of the peritoneal cavity and due to its enlargement, can cause stress on neighboring organs. Diagnosis
This condition affects less than 1% of patients with rheumatoid arthritis. The presence of three conditions: rheumatoid arthritis, an enlarged spleen (splenomegaly), and an abnormally low white blood cell count are indications that Feltys syndrome is possibly occurring. This condition as a whole is difficult to diagnose due to its complexity given a combination of disorders. It is commonly overlooked or misdiagnosed as other conditions (e.g., leukemia, systemic lupus erythrematosus) because of the rarity and lack of good understanding about it. An acronym can be used to make recognizing this disease somewhat easier:S: SplenomegalyA: AnemiaN: NeutropeniaT: ThrombocytopeniaA: Arthritis (rheumatoid)

Conditions of the blood
A complete blood count (CBC) can be done to diagnose anemia (normochromic, normocytic), thrombocytopenia, and neutropenia.
Ovarian diseases refer to diseases or disorders of the ovary.These can be classified as endocrine disorders or as a disorders of the reproductive system. If the egg fails to release from the follicle in the ovary an ovarian cyst may form. Small ovarian cysts are common in healthy women. Some women have more follicles than usual (polycystic ovary syndrome), which inhibits the follicles to grow normally and this will cause cycle irregularities. Various types of ovarian diseases exist. Some of the ovarian diseases or disorders include: endometriosis, ovarian cysts, ovarian epithelial cancer, ovarian germ cell tumors, ovarian low malignant potential tumors, and polycystic ovary syndrome (PCOS). Endometriosis
Endometriosis is a condition in which tissues lining the uterus (endometrial stroma and gland) grows abnormally beyond the uterus that may become quite painful. In simpler terms, it means that the tissue lining the uterus develops in different parts outside of it. It can be either at ovary, fallopian tubes, or peritoneal spaces.There is no single cause of endometriosis.Symptoms:
Menstrual cramps, heavy menstrual bleeding, bowel or urinary problems, nausea, vomiting, blood with stools, painful intercourse, fatigues, spotting or bleeding between periods.Treatment:

Surgery at extreme situations
Hormonal treatments using birth controls. Healthier lifestyle. Ovarian cysts
It is common for many women to develop a cyst in their lifetime. At times, these can go unnoticed without pain or visible symptoms. A cyst may develop in either of the ovaries that are responsible for producing hormones and carrying eggs in the bodies of women.
