Abstract Glomangiopericytoma (sinonasal-type hemangiopericytoma) is an uncommon sinonasal neoplasm with a perivascular myoid phenotype. This tumor differs from conventional soft tissue hemangiopericytoma in location, biologic behavior, and histologic features. The proposed cell of origin is a modified perivascular glomuslike myoid cell. Glomangiopericytoma is an indolent tumor that tends to arise in the sinonasal tract of older adults and has a low malignant potential with excellent prognosis after surgical resection. Histologically, this lesion is composed of a diffuse, subepithelial proliferation of bland, uniform, closely packed spindled cells growing in a variety of patterns. A distinctive vascular network composed of variably sized vascular channels, the smaller of which demonstrate perivascular hyalinization, is often present. We report the case of a 48-year-old woman with epistaxis and nasal obstruction who was diagnosed with glomangiopericytoma and discuss the histologic differential diagnosis.

Introduction: Winging of scapula is defined as a failure of dynamic stabilizing structures that anchor the scapula to the chest wall, leading to prominence of the medial border of scapula. It could be primary, secondary, or voluntary. Primary winging could be true winging due to neuromuscular causes or pseudo-winging due to osseous or soft-tissue masses. A scapular osteochondroma is a very rare presentation site and causes pseudo-winging leading to pushing away of the scapula away from the chest wall presenting as medial border prominence. Here, we are reporting a rare case of a scapular osteochondroma causing a pseudo-winging of the scapula. Case Report: A 2-year-old male child presented with painless, immobile, and non-fluctuant swelling over the left scapular region, insidious in onset and progressive in nature. On examination, a non-tender, immobile swelling was palpable with a painless and unrestricted range of motion at the shoulder joint. After evaluating radiographs and CT scan, the patient was diagnosed to have a ventral scapular osteochondroma leading to pseudo-winging of the scapula. Conclusion: Despite the rarity, a differential diagnosis of a scapular osteochondroma should be kept in mind while examining a young child presenting with a winged scapula. Keywords: Scapula, osteochondroma, pseudo-winging.

ABSTRACT Liposarcoma is one of the most common soft tissue sarcomas in adults, occurring in 15 to 20% of all patients with sarcoma. Primary liposarcoma of the stomach is rare. We report a case of patient with giant gastric liposarcoma who underwent surgery after a gastrointestinal bleeding. Preoperative hystopathological diagnosis was not established, even after three biopsy attempts. We discuss differential diagnosis, genetic causes, diagnosis strategies and treatment.

Primary malignant fibrous histiocytoma (MFH) of the lung is extremely rare although it is among the most common soft tissue sarcomas in adults. Surgery is the primary mode of therapy, with high rates of local and distant recurrence, while radiation therapy appears to be a very useful adjunct, decreasing local relapse. We report a case of primary malignant fibrous histiocytoma of the lung. Fourteen years after surgical resection, the patient is still alive although with multiple metastatic lesions throughout his body.

Introduction. Soft tissue mass following total hip arthroplasty raises several differential diagnoses not limited to infection, hematoma, wear debris, malignancy, and bursitis. Rice body formation in the hip region is an uncommon process denoting a chronic inflammation. We report here the second case of its kind in the medical literature of a wide symptomatic rice-like body cyst complicating a total hip arthroplasty. Case Presentation. This is the case of an 82-year-old white female, presenting with a warm, red, and inflated groin five years after revision of right total hip arthroplasty. Surgical intervention reveals a large well circumscribed cyst containing well-organized rice-like bodies. This eventuality was never reported in differential diagnosis of hip periprosthetic soft tissue masses before. Conclusion. This case report helps widening the array of the differential diagnosis in patients presenting with a slow growing soft tissue mass following total hip arthroplasty, making rice-like bodies cyst a valid one to consider.

Introduction: An amalgam tattoo is the most common form of exogenous oral pigmentation caused by the diffusion of dental amalgam into the soft tissue. Observation: Here we describe a case of diffuse pigmentation of amalgam on the hard palate. Discussion: Mucosal hyperpigmentation can occasionally be confused with melanotic lesions, thereby requiring a biopsy for differential diagnosis. Once the diagnosis of an amalgam tattoo has been established, the removal of the lesion is not necessary, except for aesthetic reasons.

Atvejis Pacientas, 37 metų, trejus metus gydytas nuo lėtinio prostatito. Prostatos sekrete nustačius atipinių ląstelių, įtarus prostatos vėžį, ligonis nusiųstas į VU Onkologijos institutą. Tyrimo pro tiesiąją žarną, cistoskopijos, rentgenologinio, ultragarso ir serumo žymenų tyrimo duomenimis, diddesnių pokyčių nerasta. Atlikus transuretrinę šlapimo pūslės gleivinės biopsiją (TUR) iš šlapimo pūslės sienelių, kaklelio ir šlaplės prostatinės gleivinės, histologiškai nustatyti normalūs urotelio audiniai. Šlapimo citologinis tyrimas buvo neigiamas. Atlikus transrektalinę prostatos biopsiją, diagnozuotas prostatos urotelio navikas, imunohistochemiškai neigiamas PSA (prostatos specifiniam antigenui) ir teigiamas citokeratinams CK8 ir CK HMW. Pacientui buvo atlikta radikali cistoprostatektomija, pašalinti dubens limfmazgiai ir suformuotas šlapimo nuotėkis į ileum segmentą, išvestą į priekinę pilvo sieną (Brycker būdu). Morfologinė diagnozė – prostatos urotelio karcinoma. Taip pat diagnozuota prostatos adenokarcinoma ir prostatos intraepitelinė neoplazija. Po 15 mėnesių PSA lygis buvo 0,2 ng/ml, jokių ligos progresavimo požymių nepasireiškė. Remiantis šiuo klinikiniu atveju straipsnyje apžvelgiama literatūra, aiškinantis prostatos urotelio karcinomos ir adenokarcinomos skirtumus. Išvados Diagnozuojant prostatos urotelio karcinomą reikia vadovautis tam tikrais kriterijais: 1) prostatos urotelio karcinoma turi būti verifikuota makro-, mikroskopiškai ir imunohistocheminiais metodais, 2) neturėtų būti kitų urotelio karcinomos židinių organizme. Būtent prostatos biopsija leidžia patologui nustatyti tikslią diagnozę prieš operaciją. Imunohistocheminis tyrimas padeda atlikti diferencinę diagnostiką. Po operacijos tiriant pašalintus audinius, diagnozė patikslinama histomorfologiškai, naudojant imunohistocheminius tyrimus, net jei ir labai retai nustatoma prostatos urotelio karcinoma.

Case report with literature overview Algimantas Sruogis1, Ugnius Mickys2, Tadas Petraitis1, Edita Kaubrienė3, Feliksas Jankevičius11 Vilnius University Institute of Oncology,Urology Department,Santariškių str. 1,LT-08661 Vilnius, LithuaniaE-mail: [email protected] Lithuanian National Centre of Pathology3 Vilnius University Institute of Oncology,Radiology Department Objective To establish criteria for the diagnosis of primary urothelial prostate carcinoma after the differential diagnosis including high-grade urothelial carcinoma extending into the bladder neck and prostate versus poorly differentiated prostate adenocarcinoma extending into the bladder. Case report The patient was a 37-year-old man with severe prostatism symptoms, who presented with an atypical seminal vesicles fluid cytological test result. The prostate was also normal by the digital examination, endoscopy, roentgenography, ultrasonography and serum markers. A diagnostic transurethral resection of bladder mucosa, bladder neck specimen revealed normal urothelial tissues. The urine cytological test result was negative. The transrectal biopsy of the prostate revealed an urothelial carcinoma with a negative staining of PSA (prostate-specific antigen) and positive of cytokeratins CK 8 and CK HMW. The patient subsequently underwent radical cystoprostatectomy and pelvic lymphadenectomy with ileal conduit m. Brycker creation. The histological diagnosis was the urothelial carcinoma of the prostate. Also, the prostate showed foci of High Grade PIN and prostate adenocarcinoma. After 15 months the patient has a PSA level of 0.2 ng/mL, no symptoms, no evidence of progression. Based on this case of the urothelial carcinoma of prostate, the literature was reviewed and the morphological differentiation between urothelial carcinoma and adenocarcinoma of the prostate was discussed. Conclusions The diagnostic criteria are the following: (1) the tumor should be a macro-, microscopically and imunohistochemically verified as urothelial carcinoma localized exclusively in the prostate gland; (2) there must be no other primary urothelial carcinoma in the body. These criteria can be readily applied when evaluating surgical resection specimens. With the use of radiologically guided or endoscopically derived biopsies, however, the pathologist is increasingly called upon to make a diagnosis before definitive surgical resection. In these circumstances, the pathologist will often resort to immunostains to help refine the differential diagnosis. Moreover, even when surgical resection specimens are evaluated, immunostains are still used in conjunction with histomorphology to confirm the diagnosis, particularly when a rare entity such as primary urothelial prostate carcinoma is encountered.
