Myoepithelial carcinoma of the salivary glands is a rare entity, with scarce amount of case reports in the literature. Due to its infrequency, its diagnosis is usually difficult and uncertain. Although there are reports of locoregional recurrences and distant metastases, its low incidence and varied biological behavior limits the clinical evidence that can be used to predict the prognosis and determine the course of treatment. We present a 23-year-old female patient without past medical history with an initial 1-year history of volume increase in the right parotid region of tumor aspect and painful on palpation. As a malignancy was suspected, a total parotidectomy was performed, reporting in the deep lobe a parotid myoepithelial carcinoma with vascular and neural invasion, negative borders, and 3–9 negative regional nodes. During her 16-year clinical evolution, she presented approximately every 2 years and a total of 9 locoregional recurrences and hepatic metastases, including cervical lymphoid nodules, temporal bone, frontal bone, and temporal fossa. Those recurrences have been treated with coordinated efforts between repeated external radiotherapy, chemotherapy, and multiple surgical resections. Myoepithelial tumors represent only 1.0–1.5% of all salivary gland tumors. The literature reports suggest a high incidence of locoregional recurrences and distant metastases in de novo myoepithelial carcinomas. Due to its rarity, treatment continues to be based on the experience of medical staff.

Abstract Background Intravenous leiomyomatosis is a rare disease. Histologically, intravenous leiomyomatosis is a benign tumor, but its biological behavior can be malignant. The development of intracardiac extensions leads to congestive heart failure and occasionally sudden fatalities. Case Description The cases of three patients treated at our university between 2017 and 2018 were studied retrospectively. Intravenous tumors extending into the right heart system were fully removed without perioperative complications or death. Only one tumor recurrence was observed during the followed-up period. Conclusion The gold standard for the treatment of intravenous leiomyomatosis with intracardiac extension is complete and successful surgical resection.

Myoepithelial carcinoma (malignant myoepithelioma) of the breast is a rare tumor, for which only a limited number of reports have been published. Most of the reports emphasized diagnosis and pathology but not biological behavior and treatment. We report a 61-year-old patient with breast myoepithelial carcinoma who developed locoregional and distant metastases and received many chemotherapy regimens. She presented with an elastic hard mass of the left breast. Breast conserving surgery was performed as part of both diagnosis and treatment. From the results of histological and immunohistochemical examinations, this case was considered to be a myoepithelial carcinoma. Fifteen months after the completion of adjuvant radiotherapy, distant metastasis of the left parasternal lymph node metastasis developed. She was treated by further excision and received a total of four regimens of chemotherapy including a combination of doxorubicin and cyclophosphamide. She received chemotherapy for 20 months after the diagnosis of metastasis.

Introduction. This paper presents two cases of very rare tumors of breast: breast sebaceos carcinoma, which has rarely been described in medical literature, and breast carcinosarcoma. Morphological characteristics and biological behavior of sebaceos carcinoma are still rather vague. Carcinosarcoma of the breast is a rare malignancy with distinct cell lines described as a breast carcinoma of ductal type with a sarcoma-like component. Case report. The first presented case is a 73-year-old female referred to our hospital in January 2008 with tumor of the right breast in the upper outer region of the breast and enlarged lymph nodes in the right axillary region. The second presented case is a 51-year-old female with carcinosarcoma, also a very rare primary breast tumor. She was admitted to our hospital in June 2011 with history of lump in the upper and lower outer quadrant of the left breast. In both cases, biopsy of tumor tissue was carried out with a thin needle, i.e. the aspiration cytology was applied as a diagnostic method, and during the operation the fast diagnostics of frozen sections and cytologic diagnostics were done. Although this methodology is important in diagnosis, in both cases it showed certain limitations in diagnosing such rare tumors. The final diagnosis was made after carefully synthesizing the histological findings and immunohistochemical phenotype. Conclusion. An accurate classification of breast tumors on cytological preparations is not possible in case of poorly differentiated and rare tumors. A careful and accurate classification of these tumors is necessary.

Multiple Recurrences

Primary adenoid cystic carcinoma (PACC) of the skin is a rare tumor with fewer than 70 cases studied in detail in the English literature. This type of tumor shows a prolonged course and a growth pattern usually manifested by multiple local recurrences and has a low potential for distant metastases. The most important modality for primary treatment is surgical resection followed by radiotherapy. We report a woman aged 43 years at the time of diagnosis, who presented with a slow-growing nodule in the right axilla without lymph node enlargement. A wide local excision was performed, and the histology revealed an adenoid cystic carcinoma. During the next 24 years, another four local recurrences were excised (the last one in 2015) and confirmed histologically to be adenoid cystic carcinoma. The patient was given 44 Gy of radiotherapy after the second surgery in 1996. PACC of the skin is a rare tumor with insufficient data concerning the efficacy of the surgical technique and chemotherapy and radiotherapy treatment, even more so in the case of multiple recurrences. After the last recurrence, the patient was offered an active follow-up based on the long tumor-free intervals in the past and because the site of the primary tumor allowed further surgical excisions in future recurrences.

Abstract Background Pulmonary artery catheter insertion is a routine practice in high-risk patients undergoing cardiac surgery. However, pulmonary artery catheter insertion is associated with numerous complications that can be devastating to the patient. Incorrect placement is an overlooked complication with few case reports to date. Case presentation An 18-year-old male patient underwent elective mitral valve replacement due to severe mitral valve regurgitation. The patient had a history of synovial sarcoma, and Hickman catheter had been inserted in the right internal jugular vein for systemic chemotherapy. We made multiple attempts to position the pulmonary artery catheter in the correct position but failed. A chest radiography revealed that the pulmonary artery catheter was bent and pointed in the cephalad direction. Removal of the pulmonary artery catheter was successful, and the patient was discharged 10 days after the surgery without complications. Conclusions To prevent misplacement of the PAC, clinicians should be aware of multiple risk factors in difficult PAC placement, and be prepared to utilize adjunctive methods, such as TEE and fluoroscopy.

Abstract Introduction Traumatic head injury with extradural hematoma (EDH) is seen in 2% of patients. Development of EDH on the contralateral side is an uncommon complication that has been reported in various case reports. Case Report We report here a case of an 18-year-old male who had a road traffic injury. He was diagnosed as a case of left-sided large frontotemporoparietal acute extradural bleed with a mass effect toward the right side. He was managed with urgent craniotomy and evacuation of hematoma. A noncontrast computed tomography (NCCT) scan performed 8 hours after postoperative period showed a large frontotemporoparietal bleed on the right side with a mass effect toward the left side. He was again taken to the operating room and right-sided craniotomy and evacuation of hematoma were performed. A postoperative NCCT scan revealed a resolved hematoma. The patient made a complete recovery in the postoperative period and is doing well. Conclusion Delayed onset epidural hematoma is diagnosed when the initial computed tomography (CT) scan is negative or is performed early and when late CT scan performed to assess clinical or ICP deterioration shows an EDH. The diagnosis of such a condition requires a high index of suspicion based on the mechanism of injury along with fracture patterns. Additionally, change in pupillary size, raised intracranial pressure, and bulging of the brain intraoperatively are additional clues for contralateral bleeding. Neurologic deterioration may or may not be associated with delayed EDH presentation. An early postoperative NCCT scan within 24 hours is recommended to detect this complication with or without any neurologic deterioration.

AbstractIntroduction: We present a case of a 29-year-old patient treated due to fully symptomatic pheochromocytoma of the right adrenal gland. Case presentation: Patient was operated on and an open right-sided adrenalectomy was performed. At the time of the surgery, a rupture of the tumor capsule occurred. Five years post-operatively, a recurrence of the symptoms of chromaffin-cell tumor was noted. After the exact localization of the multiple recurrences, the patient was reoperated on. Conclusion: The case of pheochromocytoma is presented due to the possibility of chromaffin-cell seeding into the peritoneum, with no signs of distal metastases so far.
