It can be primary (umbilical endometriosis) or secondary (after trauma or surgery, when it is called scar
endometrioma).
This article describes a rare association between MTC and
endometrioma in the same ovary and discusses imagery, pathology and treatment of this exceedingly rare entity.
Endometriomas were found in 38 cases only (Table 1).

Imaging reported acute appendicitis and
endometrioma. This serves as a reminder that an atypical clinical picture in women should also promote imaging studies with a goal of increasing diagnostic accuracy.

Ninety-two infertile Italian women with ovarian endometriosis (large
endometriomas, with a mean diameter of at least 30 mm) documented by ultrasound, who were scheduled to undergo laparoscopy 3 months later, were offered treatment with N-acetylcysteine (NAC) at a dosage of 600 mg 3 times per day for 3 consecutive days each week for 3 months.
Endometriosis is classified into one of four stages (I-minimal, II-mild, III-moderate, and IV-severe) depending on location of endometriosis implants, severity of adhesions, and size of ovarian
endometriomas. Endometriosis may be resulted from the deficiency to clear uterine lining and blood entering the pelvis during each menstrual period; however, the exact etiology of endometriosis remains unknown.
Age (years) Size (mm) Volume (mL) Simple cyst (N = 13) Mean (SD) 39,8 (13,5) 69,54 (14,02) 69,85 (59,36) Range 20-64 49-98 20-248
Endometrioma (N = 14) Mean (SD) 38,6 (14,1) 73,71 (33,26) 112,50 (111,77) Range 28-84 42-170 20-410 The size represents the largest cystic diameter measured on ultrasound.
Probably, IL-10, one of the well-known immunosuppressive cytokines, plays a role in this mechanism: we have already evidenced high level of IL-10 mRNA expression in ovarian
endometrioma samples [74,75], and this cytokine is also associated with decreased activated [CD4.sup.+] T cells in endometriotic PF.
Endometrioma is a well circumscribed mass of endometrial issue5.
