Abstract Background: Lymphoepithelioma-like carcinoma (LELC) is rare in the thymus, which is easy to be misdiagnosed. To improve its clinicopathological knowledge, we describe two cases of thymic LELC, and investigate their clinicopathological features (microscopical and immunohistochemical features), treatment and follow-up data with a review of previously published cases. Case presentation: Two patients in the First Affiliated Hospital of China Medical University underwent complete surgical resection for thymic LELC. In both, they were treated with chemotherapy or radiotherapy after operation. Histologically, tumor cells were arranged in nest-like patterns or stripe-shaped infiltration in collagen fibrous interstitial tissue containing lymphocytes. And the tumor cells were diffusely positive for broad spectrum pan-cytokeratin (CK), CK19, CD5, CD117, epithelial membrane antigen (EMA) and p63, focally positive for CD20, and negative for TdT. Recent clinical reexamine showed that the two patients were alive with no signs of recurrence.Conclusion: We report two cases of thymic LELC with a review of previously published cases to summarize the knowledge of their clinicopathological characteristics, which is necessary for the accurate diagnosis and clinical treatment.

Abstract Background Myoepithelioma-like tumor of the vulvar region (MELTVR) is a recently described mesenchymal neoplasm which typically arising in vulvar regions of adult women. Case presentation Here we report a case of a 65-year-old woman who presented with a 6-year history of subcutaneous mass in the vulvar region. The mass had recently increased in size continuously. Histologically, the tumor cells had an epithelioid to spindled shape. Epithelioid tumor cells proliferated singly or in a loosely cohesive manner with myxoid areas, while spindled tumor cells grew in diffuse sheets or storiform arrangements mainly in nonmyxoid areas. Immunohistochemically, the tumor cells were positive for vimentin, epithelial membrane antigen, calponin, and were partially mild to moderate positive for estrogen receptor, but completely negative for S100 protein, glial fibrillary acidic protein, CD34, desmin, SMA and cytokeratin. INI1/SMARCB1 expression was deficient. EWSR1 and FUS genes were intact tested by fluorescence in situ hybridization analysis. Based on these findings, we diagnose this case as MELTVR. The patient remained relapse-free after the lesion was widely excised during 8 months follow-up. Conclusions This disease should be included in the differential diagnostic list of vulvar tumors with epithelioid to spindled morphology. Recognition of its histopathological features and immunohistochemical reactivity will help to understand the tumor better.

Abstract Background Angiomyolipomas are rare mesenchymal tumours arising from the perivascular epithelioid cells consisting of variable amounts of adipose, thick-walled blood vessels and smooth muscle cells. These benign tumours commonly occur in the kidney with only a few case reports of adrenal angiomyolipomas which have the potential to reach a large size and haemorrhage. Case presentation A 45-year-old lady presented with a 3-week history of right loin pain, nausea and vomiting. A CT scan revealed a right adrenal angiomyolipoma measuring 6.3 × 6.8 cm with associated haemorrhage. The lesion was successfully treated with right open adrenalectomy, and histology confirmed the diagnosis of adrenal angiomyolipoma. The patient remained well with no evidence of recurrence at the 36-month follow-up. Conclusion Adrenal angiomyolipomas are rare benign tumours that have the ability to reach a large size and potential to bleed. Here, we report the second case of spontaneous haemorrhage in an adrenal angiomyolipoma, which was successfully treated with open adrenalectomy.

The Difference

Abstract Background Fibromuscular dysplasia (FMD) often causes renal artery stenosis with renovascular hypertension. Recent clinical outcomes encourage percutaneous transluminal renal angioplasty (PTRA) to treat FMD; however, the necessary follow-up period remains unclear. Moreover, previous studies have not revealed the difference in the period until recurrence between two major types of FMD—multifocal and focal. Case presentation We describe two patients with multifocal FMD who developed hypertension during their teenage years and had recurrence of FMD > 10 years after PTRA. We further examined the types of FMD and age of onset in 26 patients who underwent PTRA. The period until recurrence of multifocal FMD was longer than that of focal FMD. Moreover, patients with early-onset multifocal FMD are likely to have a delayed recurrence after PTRA compared to other types. Conclusions Our report suggests that patients with multifocal FMD, especially those with onset at an early age, may need long-term follow-up for at least ≥ 10 years.

Chilaiditi Syndrome

Background. Chilaiditi syndrome is a phenomenon where there is an interposition of the colon between the liver and the abdominal wall leading to clinical symptoms. This is distinct from Chilaiditi sign for which there is radiographic evidence of the interposition, but is asymptomatic. Case Presentation. Here, we present the case of a patient who, despite having clinical symptoms for a decade, had a delayed diagnosis presumably due to the interposition being intermittent and episodic. Conclusions. This case highlights the fact that Chilaiditi syndrome may be intermittent and episodic in nature. This raises an interesting question of whether previous case reports, which describe complete resolution of the syndrome after nonsurgical intervention, are perhaps just capturing periods of resolution that may have occurred spontaneously. Because the syndrome may be intermittent with spontaneous resolution and then recurrence, patients should have episodic follow-up after nonsurgical intervention.

Abstract Background: Odontogenic tumors arising from extra-alveolar sites are extremerly rare. Dentinogenic ghost cell tumor (DGCT) is an uncommon odontogenic neoplasm characterized by CTNNB1 mutation, ghost cell appearance, and dentinoid-like calcification. We present a case of an ectopic DGCT arising from a calcifying odontogenic cyst in the floor of the mouth. Case presentation: A 72-year-old man presented with a painless sublingual swelling. Imaging revealed a multi-lobulated, solid-cyst mass on the floor of the mouth. Cytology showed folded epithelial clusters composed of basaloid cells, keratinized material, and dentinoid matrix. Histology also revealed a multi-cystic, cribriform to solid nest. Immunohistochemically, CK19, CK5/6, bcl-2, and p63 were diffuse positive. CTNTTB1 mutation was detected, leading to the final diagnosis of an ectopic DGCT. There was no recurrence during a 6-month follow-up. Conclusion: This is the first report to comprehensively describe the clinicopathological features of an ectopic DGCT of odontogenic origin, developing similarly to that of a true odontogenic DGCT. Accurate diagnosis of this rare entity is necessary to avoid overtreatment.

Adverse Pregnancy

Abstract Background Symptomatic myomas during pregnancy are a rare condition that could however turn into an emergency because of torsion, necrosis, growth and compression leading to acute abdomen, potentially threating for pregnancy. Surgeons are usually reluctant to perform myomectomy during pregnancy because of an increased uterine blood flow and volume can give rise to a potential risk for haemorrhagic complications, while uterine manipulation can determine adverse pregnancy outcome. However, in some rare cases surgery is compulsory. Case presentation Here, we described a case of a successful laparotomic myomectomy performed during pregnancy at 11 weeks of gestation when an acute abdomen occurred. Surgery was followed by regular obstetrics follow-up ended with a spontaneous vaginal delivery with no pregnancy complications. Conclusion Although few case reports are described in literature, other authors have performed a myomectomy during pregnancy, and fewer cases have had a subsequent vaginal delivery, so that nowadays there is no clinical evidence on which to base best practice. This case shows that vaginal delivery after a laparotomic myomectomy performed during pregnancy, in selected cases, can be considered as a feasible option.

Fibrous Tumor

Summary Introduction: solitary fibrous tumor of the pleura (SFTP) is a rare tumor arising from mesenchymatous cells in submesothelial pleural tissue which, unlike mesothelioma, is not related to asbestos or smoking. Methods: report of four patients who underwent surgical treatment for giant SFTP and review of the pertinent literature. Results: of the four patients operated, two presented symptoms including cough, chest pain and feeling of compression, whereas the other two subjects were asymptomatic. All patients underwent complete surgical resection by wide posterolateral thoracotomy, and surgical specimens removed with minimum bleeding. None of the cases required complementary lobectomy or segmentectomy. All tumors were histologically benign. Conclusion: complete resection of the lesion is the treatment of choice in all SFTP cases. Prognosis of the benign lesion is excellent, although close follow-up is necessary. In the rarer, more aggressive forms, treatment may be complemented by adjunctive chemotherapy or radiotherapy, the benefits of which have yet to be confirmed.

Abstract Background Deficiency of factor XII (FXII) is widely considered to have a detrimental effect on pregnancy. Several reports underline the increased risk for antenatal complications with few published case reports of uncomplicated deliveries. The main objective of our article is to perform a systematic review to highlight pregnancies with severe deficiency of FXII that have been delivered uneventfully, along with presenting our relative case of a woman with severe deficiency of FXII. Materials and methods A systematic review was performed in the Pubmed database. Inclusion criteria were considered to be case reports and case series presenting delivery of uncomplicated pregnancies in women with severe FXII deficiency. Medical records of our patient were also reviewed in terms of signs and symptoms, laboratory and imaging examinations and neonatal outcomes. Results There were 62 abstracts derived while 44 were assessed for eligibility. There were finally three case reports of women with FXII deficiency delivering live newborns and one case series of 12 women with a final outcome of 19 deliveries. Regarding our case presentation, the woman with FXII levels <12%, after a neonatal death because of extreme prematurity (24 weeks + 4 days), was set in regular follow-up and treatment with bemiparin natriate, 3.5 mg/kg and acetylsalicylic acid, 100 mg/day. She finally managed to have her second pregnancy delivered at 38 weeks + 3 days, her third pregnancy ended up as a miscarriage and her fourth pregnancy was also delivered at 37 weeks + 4 days. Conclusion Despite the increased risk for antenatal complications, appropriate follow-up of pregnancies with severe FXII pregnancy may finally lead to an uneventful delivery.

We aimed to explore the optimal follow-up time for benign gastric Schwannoma. Benign gastric Schwannoma is an uncommon type of gastric neoplasias. Most of the studies are case reports and case series. Although it is generally considered to be benign, the optimal follow-up time and the chance of recurrence have not yet been investigated fully. We presented a case of benign gastric Schwannoma and systematically reviewed published case series with follow-up data. Eight studies were included, totaling 137 patients (44 male and 93 female) with the median follow-up time ranging from 22–132 months across different studies. No recurrence had been recorded during the follow-up period. Benign gastric Schwannoma rarely recurs after complete surgical resection. Long-term survival will be expected in most patients.

Abstract Background: Primary pulmonary rhabdomyosarcoma（PPRMS）in the middle-aged and elderly is a very rare event with only a few cases published. To date, only thirty-five cases of PPRMS in the middle-aged and elderly have been published. However, the analyses on clinicopathological characteristics and prognosis of PPRMS in the middle-aged and elderly have not been performed.Case presentation: We report an additional case of PPRMS in the middle-aged and elderly.Conclusions: PPRMS in the middle-aged and elderly was a highly malignant soft tissue tumor with obvious gender characteristics and significant age distribution. Pleomorphic rhabdomyosarcoma (RMS) was the most common subtype, with poor prognosis and significantly prolonged survival time after surgical resection.
