Introduction: Ectopic deciduosis refers to decidual tissue outside the uterus. Ectopic decidua appears on the surface of the female reproductive organs and peritoneum; however, rare cases can be found in the appendix, lymph nodes, lungs, kidneys, and skin. Deciduosis is a benign condition that usually does not cause any symptoms and resolves spontaneously 4-6 weeks after delivery. However, an ectopic decidua involving the appendix wall often causes appendicitis and presents with acute abdominal signs. Methodology: The descriptive study of the case report type and the data obtained from the patient's medical record. Case presentation: This paper reports a woman aged 29 years with complaints of abdominal pain, like being stabbed in the pit of the stomach and then to the lower right abdomen for two days. A physical examination revealed tenderness in the lower abdomen with a positive McBurney sign. At that time, the patient was pregnant with a gestational age of 20-21 weeks. The patient underwent an appendectomy with the tissue sent to the anatomic pathology laboratory with the presence of decidual cells in the subserous layer and serous fat, and it was concluded as deciduosis of the appendix. Conclusion: Based on clinical and laboratory findings, the patient was diagnosed with deciduosis of the appendix.

“…When this decidualization occurs outside the endometrium, it is called as ectopic decidual reaction. 1 Cases of ectopic decidual reaction has been described in ovaries, fallopian tube, cervix, uterine surface, omentum and various other abdominal organs. 2,3 Peritoneal decidual reaction is rare.…”

The occurrence of decidualization outside the endometrium, is called as ectopic decidual reaction. It can involve any abdominal organs, such as ovary, fallopian tube, cervix, uterine surface, omentum, etc. and present as grey white nodules. These nodules grossly mimic metastatic disease and granulomas, causing a diagnostic dilemma. Decidual reaction is a benign condition and can regress spontaneously in the postpartum period. Thus, it is important to accurately diagnose these lesions for optimal treatment. Histologic examination followed by immunohistochemistry can be performed on the biopsies sampled during cesarean sections, tubal ligation, appendectomy, etc. to obtain a correct diagnosis. Peritoneal location of ectopic decidua is less frequent and can be an incidental finding. Few patients may present with the symptoms of abdominal pain, hemorrhage or irritable bowel syndrome. We thereby, report a case of peritoneal ectopic decidual reaction and discuss its histopathological features, immunohistochemistry and the differential diagnosis.

Cutaneous Deciduosis: A Rare Cutaneous Lesion Mimicking Malignancy

Cutaneous deciduosis is an extremely rare condition that clinically presents as a nodular lesion in the skin as a scar or neoplasm. Histologically, this may pose a diagnostic challenge simulating malignant epithelioid neoplasms including sarcoma. Histologically, a nodular growth pattern of large monomorphic epithelioid cells is observed. The epithelioid cells in deciduosis can appear atypical with considerable nuclear pleomorphism, mimicking a malignancy. These features can be misinterpreted as a primary cutaneous or metastatic malignancy by dermatopathologists who are not familiar with gynecologic pathology. Failure to correctly diagnose this condition may result in unnecessary diagnostic studies for the patient. In this article, we report a case of cutaneous deciduosis in a 35-year-old woman with a cesarean scar. Histological examination revealed nodular proliferation of large epithelioid cells with pale eosinophilic cytoplasm and large nuclei with prominent nucleoli. Compressed atrophic slit-like glands resembling endometrial glands were present in some areas. Histopathological features of decidual cells, along with appropriate immunohistochemical studies, help establish the diagnosis and rule out other neoplastic mimics of deciduosis.
