  1. Case 06- Dr. Nisreen Abu Shahin Associate Professor of Pathology Department of Pathology, University of Jordan Amman, Jordan

  2. Case • 24 yr old nulliparus woman, no known medical disorders, not using any medications or hormones • presents to a general physician clinic with severe menorrhagia of 2 years duration causing excessive vaginal bleeding and severe anemia • She was referred to GYN clinic for evaluation

  3. Physical examination: • Pallor • Normal BMI • No palpated abdominal masses

  4. Imaging • Pelvic Ultrasound. globular large uterus with multiple uterine polyps extending into cervical os, with abnormal echogenecity. • CT Scan. marked heterogeneous uterine enlargment suspicoius for adenomyosis, along with a large heterogeneous uterine polyploid mass extending to cervical os

  6. Polypoid mass

  7. Hyalinization

  8. Differential diagnosis • Uterine tumors resembling ovarian sex cord tumors (UTROSCT) • Malignant mullerian mixed tumors (MMMT) • Endometrial stromal tumors • Epithelioid smooth muscle tumors • Endometrioid carcinoma with weird morphology

  18. Diagnosis?? • Designation from previous reports*: "corded and hyalinized endometrioid carcinoma" reflecting most striking and consistent features. • A phenotype of endometrioid carcinomas appreciated in recent decades * Young RH. Am J Surg Pathol. 2005 Feb;29(2):157-66

  24. Adenomyosis

  25. • Cervix: unremarkable

  26. Differential diagnosis??? • Familial / inherited cancer syndromes ? • Ovarian tumors secreting estrogens??

  27. • Back to patient’s family history: • Parents: consanguineous marriage • Mother died in early 40s with cancer (?multiple; ?? GIT) • A brother with GIT polyps

  28. Ovaries

  29. • Frozen sections were performed on right and left ovaries (Normal sized)

  30. Right ovary

  31. Left ovary

  32. IHCs Inhibin EMA

  33. • Ovarian stroma had multiple nodules showing annular tubules with central eosinophilic hyaline bodies and peripheral oriented nuclei (greatest diameter is at least 6mm of the examined frozen tissue). • Foci of calcification are identified.

  34. Bilateral SCTAT (SEX CORD TUMOR WITH ANNULAR TUBULES)

  35. Comments • “The presence of bilateral ovarian sex cord tumor with annular tubules is a likely source of hyper-estrogenism leading to the pathologies seen in the uterus. Moreover, the presence of the bilateral ovarian tumor raises the possibility of Peutz-Jeghers syndrome. Clinical evaluation for Peutz-Jeghers syndrome is recommended”.

  36. • Hyperpigmented lesions over the perioral region From literature

  37. Peutz-Jeghers syndrome (PJS) • inherited autosomal dominant cancer syndrome • tumor suppressor gene STK11/LKB1, 19p13.3 • mucocutaneous melanin pigmentation & hamartomatous GIT polyps • Incidence : 1 /50,000 to 1/ 200,000 live births • predisposition to: benign and malignant tumors of stomach, small intestine, pancreas, cervix, breast and ovaries.

  38. The Diagnostic Criteria for PJS is Clinical • Include: • small bowel hamartomatous polyps • characteristic mucocutaneous pigmentation • family history • Two of these criteria must be met in order to make a clinical diagnosis of PJS

  39. Cancer in PJS Banno Ee al: GYNECOLOGICAL CANCER IN PJS. Oncology Letters (2013) 6: 1184-1188.

  40. PJS – GIT tumors • Non malignant: P-J hyperplastic polyps; ? Tubular adenomas • malignant GIT: • large intestine>> stomach> small intestine > pancreas (mucinous adenocarcinomas)

  41. PJS- GYN tumors • highest in cervix >> ovary • ovarian, cervical and breast cancers: surveillance is necessary - Minimal deviation adenocarcinoma (MDA) - SCTAT (“ in PJS is commonly multifocal, bilateral, small (detected microscopically), and calcified in >50% of cases)”* Scully RE et al. Cancer .1982 - Mucinous and serous epithelial ovarian tumors ↑ ( benign, borderline, malignant ) • lifetime risk of endometrial CA in PJS reported ≈ 9% • 10-18 times >> general population • simultaneous multiple gynecological tumors (current case)

  42. Current Case • Simultaneous GYN tumors?  PJS germline STK11 gene mutation linked to both ?  hyper-estrogenism caused by SCTAT lead to endometrial hyperplasia/ cancer ?
