RESUMO
Metastatic gallbladder carcinoma to the ovaries is occasional but a recognized entity. It can mimic, clinical and morphologically, a primary ovarian tumor, challenging the diagnosis. We present the case of a patient with a lump in the hypogastrium extending into the right iliac fossa and was found to have abdominopelvic cystic lesion with enhancing solid components and multiple sub-centimetric and ill-defined abdominal lymph nodes. Also, subpleural and parenchymal nodules in the lungs were present. She subsequently underwent a laparotomy. Cholecystectomy was also done due to pre-existing symptomatic biliary lithiasis. The histologic report described the ovarian involvement as metastases from a gallbladder carcinoma. The presentation of ovarian metastases can challenge the diagnosis. Hence, careful evaluation of the digestive tract and judicious use of immunohistochemistry should be considered in patients presenting with ovarian masses.

Myositis ossificans (MO) is a benign, ossifying lesion that usually affects the skeletal muscle. The rare non-traumatic form of MO can cause diagnostic dilemma and management issues. These lesions, however, have similar radiology and histopathological characteristics described in the more frequently encountered traumatic forms. Depending on the stage of the lesion, the inherent feature of myositis ossificans varies, and so does the management of the lesion. We describe a non-traumatic MO occurring in latissimus dorsi of a young girl and discuss the review of literature on this rare subtype.

Papillary endothelial hyperplasia (Masson's tumour) is a reactive proliferation of endothelium producing papillary structures with fibrovascular cores. Dilatation, stasis and accompanying inflammation have been incriminated as the inciting events, evident by the presence of this lesion in haemorrhoids, urethral caruncles and laryngeal polyps. We present here a case of papillary endothelial hyperplasia in angiokeratoma hitherto undescribed despite sharing common etiopathogenetic features of dilatation and stasis with other aforementioned lesions.
