We report a 45-year-old patient, who has systemic arterial hypertension in treatment, was admitted for abdominal pain in the epigastrium, with irradiation to the right hypochondrium, accompanied by nausea and vomiting of 10 occasions of bile content, physical examination with pain in the right hypochondrium, Murphy positive. We have laboratory studies with a lipase of 788, so a diagnosis of pancreatitis is made with an etiology to be determined. The laboratories suggestive of acute biliary pancreatitis (lipase 788.71);an imaging study was subsequently performed (ultrasonography) with the result of stone in the common bile duct. A laparoscopy was performed with relative improvement, so he was discharged and returned 20 days after surgery due to abdominal pain of the same intensity in the left hypochondrium.

We report on a 59-year-old female patient, who was admitted to the hospital due to the discovery of bilateral breast masses for 3 months, there was no paresthesia or dyskinesia. The patient accidentally found a mass in the right upper mediastinum while completing a plain chest X-ray, initially suspected as a benign neurilemmoma on CT. Surgical resection and pathological analysis confirmed an intraneural hemangioma. Unexpectedly, the patient developed new-onset right upper limb numbness and paresthesia 3 months post-operatively, probably related to surgical nerve injury. This case underscores the importance of maintaining a broad differential for mediastinal masses, and the potential for iatrogenic neurological complications when managing these rare, yet vascular lesions.展开更多

The current first-line treatment for IH is oral propranolol;however, some studies recommend intralesional corticosteroid injections for small, limited, deep, or prominent tumors because of concern regarding serious systemic complications related to propranolol. This review summarizes and analyzes the current clinical studies on corticosteroid injections in IHs, discusses treatment norms, and explores future research directions.展开更多

文摘BACKGROUND Giant hepatic cavernous hemangioma with multiple satellite nodules is a rare subtype of hepatic cavernous hemangioma,the most common vascular liver tumor.We report on a tumor with unusual histologic features:(1)Finger-like infiltration pattern;(2)lack of encapsulation;(3)blurred tumor/liver interface;and(4)massive satellitosis-referring to the article“Hepatic cavernous hemangioma:underrecognized associated histologic features”.CASE SUMMARY A 60-year-old man presented with increasing uncharacteristic abdominal discomfort and mildly elevated blood parameters of acute inflammation.Imaging revealed an unclear,giant liver tumor of the left liver lobe.A massive vascular tumor with extensive satellitosis broadly infiltrating the adjacent liver parenchyma was resected via hemihepatectomy of segmentsⅡ/Ⅲ.Histopathological diagnosis was giant hepatic cavernous hemangioma with multiple satellite nodules,featuring unusual characteristics hardly portrayed in the literature.Retrospectively,this particular morphology can explain the difficult pre-and perioperative diagnosis of a vascular liver tumor that is usually readily identifiable by modern imaging methods.CONCLUSION This case emphasizes the exact histological workup of tumor and tumor-induced parenchyma changes in radiologically unclassifiable liver tumors.
文摘BACKGROUND Congenital infantile fibrosarcoma(CIF)and congenital hemangioma(CH)have similarities on prenatal ultrasound and are rare.CASE SUMMARY We report 3 cases of fetuses with superficial hypervascular tumors,confirmed by postnatal pathology as CIF(1 case)and CH(2 cases,including 1 in a twin fetus).In Case 1,a mass with a rich blood supply in the fetal axilla was discovered by prenatal ultrasound at 28+0 wk of gestation.The postpartum pathological diagnosis was CIF,the mass was surgically removed,and the prognosis of the child was good.In Case 2,at 23+1 wk of gestation,a mass was discovered at the base of the fetus’s thigh on prenatal ultrasound.The postpartum pathological diagnosis was CH.After conservative treatment,the mass shrank significantly.Case 3 occurred in a twin fetus.At 30+0 wk of gestation,prenatal ultrasound revealed a bulging mass with a rich blood supply on the abdominal wall of one of the fetuses.Three weeks later,the affected fetus died,and the unaffected baby was successfully delivered by emergency cesarean section.The affected fetus was pathologically diagnosed with CH.CONCLUSION Prenatal ultrasound can provide accurate information,such as the location,size and blood supply of a surface mass in a fetus.We found similarities between CIF and CH in prenatal ultrasound findings.Although it is difficult to distinguish these conditions by prenatal ultrasound alone,for superficial hypervascular tumors that rapidly increase in size in a short period,close ultrasound monitoring of the fetus is required to quickly address possible adverse outcomes.
文摘BACKGROUND Pancreatic cavernous hemangioma(pCH)is a rare type of benign vascular tumor.Making the right diagnosis is challenging due to low clinical suspicion and the lack of existing cross-sectional imaging tools to distinguish it from other pancreatic lesions.CASE SUMMARY We describe a male patient,age 18,who presented with a pCH.Computed tomography,magnetic resonance imaging,and ultrasound showed cystic space in the tail of the pancreas.A dark spot sign on the T2 weighted image sequence was observed.Clinically,a mucinous cystic neoplasm with hemorrhage was suspected preoperatively by combining imaging,and the operative indication was clear.The patient underwent a distal pancreatic tumor resection under laparoscopic control.Immunohistochemical staining for CD31 and CD34 was positive;D2-40 was positive in interstitial lymphatic vessels and negative in vascular epithelial cells;and calcium-binding protein was negative.The results support the diagnosis of pCH combined with chronic intracapsular spontaneous hemorrhage.No complications or recurrences were observed during the follow-up period.CONCLUSION Chronic spontaneous hemorrhage may occur in pCH,which may greatly influence the accuracy of diagnosis using imaging modalities.Surgical resection for uncertain pCH seems reasonable with a good outcome.
