Catamenial-related thoracic pain. (A) At surgery, several blue-brown lesions involving the diaphragmatic dome were seen. (B) Pathologic macroscopic examination of the corresponding resected diaphragmatic specimen showed a very thick diaphragm containing (C) several cystic lesions. (D) Image of a whole slide containing microtome section of a diaphragmatic resection from a patient with chronic catamenial pain; dilated glands inside a thick diaphragm are evident (left panel) without magnification. For comparison (right panel) is a sample of surgical specimen of a “normal” diaphragm (hematoxylin and eosin; no magnification). (E) At histology, cystic lesions corresponding to a dilated endometrial gland surrounded by endometrial stroma were observed (hematoxylin and eosin; original magnification ×100). (F) A high magnification of a cystic endometrial gland staining positively for progesterone receptor.

Endometriosis-related diaphragmatic hernia. (A) Chest radiograph and (B) computed tomography scan show a right-sided diaphragmatic hernia (yellow arrows) in a patient with endometriosis-proven diaphragmatic involvement. At pathology examination, no gland but (C) endometrial stroma staining positively for (D) progesterone receptor was present in the surgical specimen (original magnification ×100).

Catamenial-related hemothorax. (A) Chest radiograph showing a massive right-sided pleural effusion in a patient with catamenial recurrent hemothorax. (B) At pathology study, no gland was found in this case but only lymphocyte and plasmocyte infiltrate with siderophages (hematoxylin and eosin; original magnification ×200). (C) Pearl’s staining shows hemosiderin-laden macrophages, and (D) progesterone receptor staining shows endometrial stromal cells. Magnification ×200.
