RESUMO

Primary cutaneous large B-cell lymphoma (Bcl) is defined as a lymphoma composed of large cells constituting more than 80% of the infiltrate and absence of extracutaneous involvement after staging investigations. In the new World Health Organization/European Organization for Research and Treatment of Cancer classification, cutaneous Bcls with large cells are of three types - primary cutaneous large Bcl leg type (PCLBCLLT), primary cutaneous follicle center lymphoma diffuse type (PCFCLDT), and primary cutaneous large Bcls other (PCLBCLO). These three different types are distinct in terms of their clinicopathological features and survival. The PCLBCLO has intermediate features between those of PCLBCLLT and PCFCLDT. We present a case of PCLBCLO in a 57-year-old male who presented with a scalp swelling. Ultrasonography examination was suggestive of a sebaceous cyst. Computed tomography scan revealed the presence of an ill-defined hyperdense region in the soft tissue of the scalp region extending into the deeper layers of the scalp. Fine-needle aspiration cytology (FNAC) revealed the presence of atypical lymphoid cells. Diagnosis was confirmed by biopsy and immunohistochemistry. Patient received rituximab combined with doxorubicin, vincristine, cyclophosphamide, and prednisolone regimen with complete resolution of the lesion. We present this case for its rarity, the utility of FNAC in early diagnosis, and to discuss the differential diagnosis.

RESUMO

Vascular malformations (VMs) are structural malformations of vascular development causing soft tissue abnormality with functional and esthetic impairment. They are named by their predominant vessel type as arterial, venous, lymphatic or mixed types. VMs of the parotid gland are extremely rare and constitute a distinct entity of parotid pathology that requires specific diagnostic tools and management. Till 2013, only fifty cases of VMs of the parotid have been described in the literature. We present a case of a venolymphatic malformation of the parotid gland extending into the parapharyngeal space in a 21-year-old male who presented with a swelling on the left side of the face extending into the neck. Diagnosis was suggested by ultrasonography and computed tomography scan and was confirmed by magnetic resonance imaging examination. Complete surgical excision of the lesion was done with a favorable outcome. Diagnosis was confirmed based on histopathology and immunohistochemical studies.

RESUMO

Papillary cystadenocarcinoma (PCAC) is a rare salivary gland tumor characterized by a predominantly cystic growth that often exhibits intraluminal papillary growth without specific histologic features of other cystic salivary gland tumors. The preoperative cytological diagnosis can pose a diagnostic challenge as it has to be differentiated from other cystic papillary tumors such as mucoepidermoid carcinoma, papillary cystic variant of acinic cell carcinoma, and low-grade cribriform CAC. It is considered to be a low-grade malignant salivary gland tumor with an indolent biological behavior. We report a case of PCAC of the parotid in a 55-year-old male diagnosed on fine needle aspiration cytology. Although it showed mild atypia cytologically, on excision tumor showed vascular and perineural invasion with regional node metastasis indicating a wider morphologic spectrum than what is described. This prompted us to write a case report describing the cytological and histological features of this rare tumor and also discuss the diagnostic challenges.

RESUMO

BACKGROUND: In the assessment of poststroke functional outcome, there are 2 alternative approaches to rating patient independence in motion: (1) focusing solely on patient ambulation (discounting self-use of wheelchair) and (2) focusing broadly on patient mobility (counting self-use of wheelchair). This study was undertaken to create and assess the inter-rater reliability of a version of the Rankin Focused Assessment (RFA) that focuses on ambulation (Rankin Focused Assessment-Ambulation [RFA-A]), as an alternative to the original RFA that focused on mobility (Rankin Focused Assessment-Mobility [RFA-M]). METHODS: The RFA-A was created by changing instructions in the RFA-M for handling of nonambulatory, wheelchair-using patients. Paired study coordinators then applied the RFA-A to 50 consecutive patients enrolled in a phase 3 acute stroke trial. RESULTS: Among the 50 patients, the mean age was 72 years (range 43-93) and 48% were female. Overall, study coordinator pairs assigned the same modified Rankin Scale (mRS) grades to 48 of the 50 patients, yielding a weighted κ of .98 (95% confidence interval [CI] .96-1.00) and an unweighted κ of .95 (95% CI .89-1.02). At day 90, 43 patients were alive and 7 had died. Among surviving patients, the weighted κ was .98 (95% CI .95-1.00) and the unweighted κ was .94 (95% CI .86-1.02). The κ values for all 6 dichotomizations of the mRS score ranged from .93 to 1.00. CONCLUSIONS: The RFA-A demonstrates high inter-rater reliability in grading global functional outcome. The RFA-A is a useful tool for assigning an mRS score in research and clinical practice when functional assessment focused on ambulation is desired.

RESUMO

Serous papillary cystadenofibromas (SPCAFs) of the fallopian tube are very rare benign tumors of the female genital tract. They are usually asymptomatic and are found incidentally. Until now, only 18 cases of this tumor have been reported in the world literature. We report a case of SPCAF of the left fallopian tube in a 30-year-old female who presented with a large abdominal mass and pain. On computed tomography, a diagnosis of ovarian neoplasm was given. However, during surgery the tumor was found to arise from the fallopian tube and was treated with tubal cystectomy with sparing of the ovary. We present this unique case on account of its rarity, unusual presentation, and huge size along with a short review of literature.

RESUMO

Pemphigoid vegetans is a very rare type of bullous pemphigoid which usually affects the elderly and has not been reported in children. It shows a clinical resemblance to pemphigus vegetans but has distinct histological and immunopathological features of bullous pemphigoid. A 9-year-old girl presented with recurrent purulent and verrucous vegetating lesions on her forehead, groin and vulva along with scaling, crusted, bullous and purulent lesions on the eyelids, periorbital, periauricular, perioral region and lips. She had oral lesions and a cerebriform tongue. Though she showed clinical features of pemphigus vegetans, histology revealed a subepidermal blister with the absence of acantholysis. Direct immunofluorescence studies were suggestive of bullous pemphigoid. On clinicopathological correlation, a diagnosis of pemphigoid vegetans was made. She responded well to oral corticosteroids and dapsone therapy with complete resolution of the lesions.

RESUMO

Pure uterine lipoma is a rare entity with only a few cases having been reported in the literature. They usually develop in postmenopausal woman and are mistaken for leiomyomas both clinically and on ultrasound examination. Magnetic resonance imaging (MRI) is the best modality for its preoperative diagnosis. Uterine lipoma has been reported in association with other lesions like endometrial carcinoma, cervical carcinoma and struma ovarii. We present a case of pure lipoma of the uterus with a coincidental benign brenners tumor of the ovary in a 60-year-old female. Patient presented with pain in the abdomen and a preoperative diagnosis of leiomyoma was made based on ultrasonography findings. Gross examination revealed a fatty tumor with a nodule in the right ovary. Microscopy confirmed the presence of pure uterine lipoma with a co-existent brenners tumor of the ovary. To the best of our knowledge this is the first case of uterine lipoma to be reported in association with ovarian brenners tumor.

RESUMO

Myoepithelial carcinoma (MC) is a rare neoplasm of the salivary gland generally occurring in the parotid gland and rarely in the minor salivary glands. It poses a diagnostic challenge on fine-needle aspiration (FNA) cytology because it can show different cell types and lack clear features of malignancy. This can lead to a range of differential diagnosis on cytology. The diagnostic difficulty can be compounded if the lesion is present at an unusual site. A 41-year-old male presented with a recurrent swelling on the check since 2 years with a prior history of pleomorphic adenoma (PA) at the same site 8 years back. FNA was performed and a diagnosis of recurrent PA or myoepithelial cell neoplasm was given. Final diagnosis was made on histology and immunohistochemistry studies and reported as MC of minor salivary gland originating within PA. Pathologist should be aware of the occurrence of MC at the sites of the minor salivary glands in the oral cavity and its wide morphologic spectrum to make a confident diagnosis of MC preoperatively.

RESUMO

BACKGROUND AND PURPOSE: Early reperfusion is the most effective therapy for both acute brain and cardiac ischemia. However, the cervicocephalic circulatory bed offers more challenges to recanalization interventions. The historical development of reperfusion interventions has not previously been systematically compared. METHODS: Medline search identified all multi-arm, controlled trials of coronary revascularization for acute myocardial infarction and multicenter trials of cerebral revascularization for acute ischemic stroke reporting angiographic reperfusion rates. RESULTS: Thirty-seven trials of coronary reperfusion enrolled 10 908 patients from 1983 to 2009, and 10 trials of cerebral reperfusion enrolled 1064 patients from 1992 to 2009. Coronary reperfusion trials included 10 of intravenous fibrinolysis alone, 8 combined intravenous fibrinolysis and percutaneous transluminal coronary angioplasty with or without stenting, 3 intra-arterial fibrinolysis, and 16 percutaneous transluminal coronary angioplasty with or without stenting. Cerebral reperfusion trials included 1 of intravenous fibrinolysis alone, 3 intra-arterial fibrinolysis, 3 endovascular device alone, and 3 of endovascular treatment ± intravenous fibrinolysis. In both circulatory beds, endovascular treatments were more efficacious at achieving reperfusion than peripherally administered fibrinolytics. In the coronary bed, rates of achieved reperfusion began at high levels in the 1980s and improved modestly over the subsequent 3 decades. In the cerebral bed, reperfusion rates began at modest levels in the early 1990s and increased more slowly. Most recently, in 2005 to 2009, cardiac reperfusion rates substantially exceeded cerebral, partial reperfusion 86.1% versus 61.1%, complete reperfusion 78.6% versus 23.4%. CONCLUSIONS: Reperfusion therapies developed more slowly and remain less effective for cerebral than cardiac ischemia. Further, cerebral circulation-specific technical advances are required for physicians to become as capable at safely restoring blood flow to the ischemic brain as the ischemic heart.
