N Gómez Gabaldón, C Manzanares Arnaiz, L Noguero Cánovas, J Juan Armas
Acute rhinosinusitis is an important health problem. Even though its frequency is not well documented in our country?, the economic burden it bears is not insignificant as it notably alters the quality of life of affected patients. Its diagnosis is generally clinical in nature, with further studies reserved only for the differential diagnoses of complications or tumour-like processes. The most frequent causes are viral infections, although Streptococcus pneumoniae and Haemophilus influenzae are the most commonly isolated bacterial agents...

Multifunctional nano-biomaterials with the integration of diagnostic and therapeutic functions have shown great promise in improving the efficacy of cancer therapy. Herein, a new nanoplatform based on functionalized Cu 3 BiS 3 nanoparticles (NPs) is fabricated for tumour-targeted combination phototherapy. The as-synthesized hydrophobic Cu 3 BiS 3 NPs are modified with DSPE-PEG/DSPE-PEG-NH 2 , followed by the conjugation of the photosensitizer chlorin e6 (Ce6) and the target ligand folic acid (FA). The introduced Ce6 can further form a chelate complex with Gd 3+ ...

Background: Liposarcoma is an extremely rare primary bone sarcoma. Case presentation: We report a case of primary pleomorphic liposarcoma that arose in an 18 year old male in the metaphysis of the left tibia. Plain radiographs showed a partly sclerotic lesion and MR imaging a heterogeneous tumour predominantly isointense on T1- and high-signal on T2-weighted sequences with focal areas of increased T1 signal that suppressed with fat saturation. PET/CT showed marked FDG uptake (SUV = 17...

Renal cell carcinoma is one of the most common tumours to spread by extranodal metastases to the head and neck. Metastatic renal cell carcinoma to the head and neck area has been demonstrated mostly in the paranasal sinuses, parotid gland, the mandible, larynx and hypopharinx. Renal cell carcinoma should be excluded whenever a metastatic lesion is encountered in the head and neck area, even if the metastatic lesion is the first clinical presentation. The diagnosis of metastatic RCC should be suspected in any patient with even a remote history of renal cell carcinoma...

Ovarian smooth muscle tumours are rare. Notable myxoid change in smooth muscle tumours is uncommon, and raises diagnostic issues that need to be considered on evaluating a spindle cell lesion with notable myxoid change. There is only one case of myxoid leiomyoma of the ovary previously reported. We here report a case of ovarian leiomyoma with areas of myxoid stroma and discuss the relevant differential diagnosis and histological features to be assessed in such a lesion.

BACKGROUND AND OBJECTIVES: The standard treatment for cutaneous squamous cell carcinoma (cSCC) is wide local excision (WLE). Incomplete tumor excision is associated with increased recurrence rates and mortality risk. Risk factors for positive margins after WLE of cSCC has been examined in only a few studies. We sought to assess the influence of several clinicopathological factors on margin status in the largest cSCC population to date. METHODS: We performed a retrospective review of records at two skin cancer clinics identifying patients with biopsy-proven cSCC who underwent WLE...

Bazex syndrome (BS) is a rare paraneoplastic syndrome most frequently associated with squamous cell carcinomas of the upper aerodigestive tractand other tumours. Characteristically, cutaneous lesions precede the diagnosis of malignancy. We report a 72-year-old patient with 1-year history of acral dermatitis. The diagnosis of BS was based on the presence of psoriasiform acral dermatitis and the evidence of two simultaneous tumors (prostate adenocarcinoma and undifferentiated carcinoma ofthe submandibular gland)...

Bladder schwannoma is a rare tumour arising from Schwann cells in nerve sheaths. It is usually more common in patients diagnosed with neurofibromatosis. However, isolated cases of urinary bladder schwannoma is incredibly rare, attributing to <0.1% of bladder tumours. A literature review and analysis revealed that it presents in adulthood, is mostly symptomatic and diagnosis is established histologically. We report a case of isolated bladder schwannoma in 25 year-old female who presented with dyspareunia.

Extranodal follicular dendritic cell sarcoma (FDCS) is a very rare tumour, only reported in case reports and case series. It poses diagnostic and management challenge both to the clinician and pathologist. We present such a rare case of duodenal FDCS in a 56-year-old woman who was recently managed in our institution. Repeated pre surgical biopsies were non-diagnostic and the final diagnosis was made only after surgical excision of the tumour and with the help of histopathological and immunohistochemical studies...

Small intestinal endocrine tumours (SI-NETs) are generally considered resistant to systemic treatment. To date, predictive markers for drug activity are lacking. Tumour samples from 27 patients with SI-NETs were analyzed ex vivo for sensitivity to a panel of cytotoxic drugs and targeted agents using a short-term total cell kill assay. Samples of renal cancer, colorectal cancer (CRC), ovarian cancer, and chronic lymphocytic leukemia (CLL) were included for comparison. For the SI-NET subset, drug sensitivity was analyzed in relation to clinico-pathological variables and pre-treatment biomarkers...

AIM: Fibroepithelial lesions (FELs) of the breast span a morphological continuum including lesions where distinction between cellular fibroadenoma (FA) and benign phyllodes tumour (PT) is difficult. The distinction is clinically important with FAs managed conservatively while equivocal lesions and PTs are managed with surgery. We sought to audit core biopsy diagnoses of equivocal FELs by digital pathology and to investigate whether digital point counting is useful in clarifying FEL diagnoses...

PURPOSE OF REVIEW: The aim of this study was to summarize the role of recently developed diagnostic techniques in the diagnosis and management of patients with small bowel tumours (SBTs). RECENT FINDINGS: Recent studies show that the overall SBT incidence is increasing. The introduction of small bowel dedicated diagnostic tools [i.e. capsule endoscopy, device-assisted enteroscopy (DAE), computed tomography (CT) and MRI-enterography] might partially explain this trend...

Nasopharyngeal angiofibroma (NA) is a benign, highly vascularised tumour of the nasopharynx, which typically occurs in young males aged 14-25 years. We report an interesting case of an NA arising de novo in a 32-year-old male. He was referred to our facility for severe nasal haemorrhage after biopsy of a left nasopharyngeal mass. In the operating room, extensive bleeding was noted, and an endoscopic medial maxillectomy was performed, and the left internal maxillary artery was ligated allowing for near total resection of the lesion...

Diagnosis of endometrial cancer is primarily based on symptoms and imaging, with early-stage disease being difficult to diagnose. Therefore, development of potential diagnostic biomarkers is required. Metabolomics, a quantitative measurement of the dynamic metabolism in living systems, can be applied to determine metabolite profiles in different disease states. Here, serum metabolomics was performed in forty-six early stage endometrial cancer patients and forty-six healthy volunteers. In addition, the effect of identified metabolites on tumour cell behavior (invasion, migration, proliferation, apoptosis, autophagy), was examined in endometrial cancer cell lines...
