Pediatric IgG4-related dacryoadenitis and sialadenitis (Mikulicz's disease) with acquired hemophilia A: A case report and review of literature.

We report a case of IgG4-related dacryoadenitis and sialadenitis (Mikulicz's disease) with acquired hemophilia A (AHA) in a pediatric patient. An 11-year-old female presented with intermittent swelling of the bilateral upper eyelids and neck areas. Clinical examination revealed bilateral swollen upper eyelids with palpable mass lesions in the lacrimal fossa.

Histopathological growth pattern and vessel co-option in intrahepatic cholangiocarcinoma.

Intrahepatic cholangiocarcinoma (iCCA) exhibits different blood imaging features and prognosis depending on histology. To clarity histopathological growth patterns (HGPs) and vascularization processes of iCCA, we collected 145 surgical specimens and histologically classified them into large bile duct (LBD) (20 cases), small bile duct (SBD) (54), cholangiolocarcinoma (CLC) (35), combined SBD-CLC (cSBD-CLC) (26), and ductal plate malformation (DPM) (10) (sub)types. According to the invasive pattern at the interface between tumor and adjacent background liver, HGPs were classified into desmoplastic, pushing, and replacing HGPs.

Primary hepatobiliary mucoepidermoid carcinoma: a case report and review of literature.

Hepatobiliary mucoepidermoid carcinoma is a rare malignant tumor comprising mucous, intermediate, and epidermoid cells. Herein, we presented a case of primary liver mucoepidermoid carcinoma preoperatively misdiagnosed as conventional intrahepatic cholangiocarcinoma. A 67-year-old male was admitted to our hospital.

Primary Hepatic Schwannoma: Case Report and Literature Review.

Primary hepatic schwannoma is an extremely rare tumor with a good prognosis. Preoperative diagnosis is often challenging due to nonspecific clinical symptoms and its rarity. Here, we report a case of a 56-year-old male patient misdiagnosed with malignant liver tumor, later identified as primary hepatic schwannoma.

Synchronous rectal adenocarcinoma and intestinal mantle cell lymphoma: A case report.
