Solitary Ulcerated Lesion on the Arm.

Presumed Solitary Circumscribed Retinal Astrocytic Proliferation in the Fovea With OCT Angiography: A Misnomer.

The retinal lesion known as the presumed solitary circumscribed retinal astrocytic proliferation (pSCRAP) is a benign retinal tumor. Although many of the clinical characteristics of the lesion have been described, much about the pathogenesis of this uncommon tumor is not yet known. Here, the authors report a pSCRAP lesion in the fovea with secondary vision loss occurring in middle age. Structural optical coherence tomography (OCT) scans indicate that the lesion arises from the deep retina or retinal pigment...

Solitary pulmonary capillary hemangioma: An under-recognized pulmonary lesion mimicking early lung cancer on computed tomography images.

Solitary pulmonary capillary hemangioma (SPCH) is a rare lung tumor typically presenting as pure or part-solid ground-glass nodules (GGNs) on computed tomography (CT), which clinically resembles early lung cancer.

Epstein-Barr Virus Positive Mucocutaneous Ulcer: A Case Report.

Epstein-Barr virus (EBV) is known to be associated with B-cell lymphoproliferative disorders, and EBV-positive mucocutaneous ulcer (EBV-MCU) is a recently described entity observed in immunocompromised individuals. EBV-MCU is an aggressive appearing ulcerated lesion seen in the skin, oral cavity, and gastrointestinal tract. The process has Hodgkin-like features with a self-limited, indolent course, generally responding well to conservative management. We present a case of EBV-MCU recently encountered in a 5...

Dermoscopic features of clear cell acanthoma.

Clear cell acanthoma is an uncommon type of benign epithelial tumor. Typically, it is a solitary lesion found on the lower limbs. It presents as a nodule or small plaque with slow and well-defined growth. Diagnosis used to be clinical and histopathological, but the advent of dermoscopy has led to an increase in diagnostic accuracy. We describe a case in which dermoscopy proved highly useful for diagnosis of the lesion.

Spontaneous regression of Merkel cell carcinoma.

A 96-year-old woman presented with a rapidly enlarging lesion overlying the suprasternal notch. The lesion originated as a small, erythematous, scaly macule that rapidly increased in size over 8 weeks and became an ulcerated nodule measuring 5 cm in diameter and 4.5 cm in thickness. A 4-mm punch biopsy showed a poorly differentiated tumor with cells that were positive for CAM 5.2 and cytokeratin 20 in a dotlike paranuclear pattern and negative for cytokeratin 5/6, human melanoma black 45, and leukocyte comm...

PET/CT Imaging for Solitary Primary Bone Lymphoma of Thoracic Vertebra.

Primary bone lymphoma without classic nodal lesions or advanced disease may be mistaken for other osseous diseases, especially when involving a single bone site. In this patient, a series of imaging modalities including MRI, bone scan, and F-FDG PET/CT revealed only 1 solitary osseous lytic lesion with abnormal uptake in the third thoracic vertebra, suggesting a primary skeletal malignancy. The subsequent histopathologic examination confirmed the diagnosis of diffuse large B-cell lymphoma. After chemotherap...

TERT Promoter Mutations in Solitary Fibrous Tumor.

TERT promoter mutations have been reported in 22% of solitary fibrous tumors (SFT) and have been associated with poor outcomes. We performed testing for TERT hotspot mutations in a large series of solitary fibrous tumors in order to confirm this finding and explore clinicopathologic correlates of mutation status.

Recurrent giant cell tumour of the maxillary sinus and pterygoid process treated with denosumab.

We report the case of a 74-year-old man with a giant cell tumour (GCT) of the right maxilla and pterygoid process. The patient presented to the maxillofacial and head and neck surgery clinic with an ulcerated lesion of the hard palate. Initial workup with CT revealed a mass within the right maxillary sinus and pterygoid process with associated bone expansion and erosion. Biopsy showed a GCT with mucosal ulceration. Two years after surgical resection, a follow-up CT revealed tumour recurrence involving the r...

MRI features in solitary cerebral Langerhans cell histiocytosis : a case report and review of literature.

In this study, we report a case of solitary Langerhans cell histiocytosis (LCH) without skull or systemic lesions, including reviewing the initial magnetic resonance (MR) findings of cerebral LCH. A 36-year-old male patient presented with generalized tonic-clonic type seizure. Brain MR imaging showed a 3cm mass lesion involving the right frontal lobe. It showed iso-intensity on T1-weighted images and hyperintensity on T2-weighted images. After gadolinium enhancement, the mass showed heterogeneous enhancemen...

Tumor-to-tumor metastasis of lung adenocarcinoma into a spinal intradural solitary fibrous tumor: a case report.

Solitary fibrous tumors (SFTs) are rare mesenchymal neoplasms commonly involving visceral or parietal pleura. We present the first report of tumor-to-tumor metastasis involving a pulmonary adenocarcinoma donor and an intradural SFT recipient. The patient presented with a 1 year history of diffuse back pain. A spinal intradural contrast-enhancing mass at the T9/10 level and a tumor of the lung were diagnosed radiologically. Bronchoscopic biopsy confirmed pulmonary adenocarcinoma in the right upper lung lobe...

Wound myiasis: the role of entodermoscopy.

Although wound or traumatic myiasis is common in tropical countries, only recently cases associated with underlying dermatoses, such as seborrheic dermatitis and psoriasis, have been reported. We describe a patient with seborrheic dermatitis and an ulcerated lesion on the scalp, in which the dermatological examination with the aid of dermoscopy allowed the identification of larvae (maggots) compatible with infestation by Cochliomyia hominivorax. Treatment was performed with oral and topical ivermectin, foll...

Ripple-Pattern Sebaceous Trichoblastoma.

A 28-year-old man of Middle-Eastern descent presented with a raised, pearly, slightly pigmented lesion on the right nasal ala. The lesion had been present for approximately 4 months. An excisional biopsy was taken, and the lesion measured 1.0 cm × 0.9 cm in dimension. The cut surface revealed a firm, white to tan nodule located within the dermis. The patient had no other significant medical history. After the initial excision, the lesion did not recur.

Solitary fibrous tumor of thyroid: a case report with review of literature.

Solitary fibrous tumors are rare spindle cell tumors of mesenchymal origin most commonly found in the pleura and peritoneum. In contrast, extra-serosal locations are rare. We present a 41-year-old female with a progressively enlarging left-sided neck mass of one-year duration with subsequent rapid-onset growth over two months, and was pathologically confirmed to be a benign solitary fibrous tumor of the thyroid gland.

Clinical outcomes of solitary atrial flutter patients using anticoagulation therapy: a national cohort study.

Anticoagulation therapy is indicated to prevent stroke in atrial flutter (AFL) and atrial fibrillation (AF) patients. However, the outcomes of solitary AFL patients may differ from those with AFL who develop AF during follow-up. This study aimed to investigate the differences in clinical outcomes: (i) among patients with solitary AFL, AF, and AFL developing AF thereafter and (ii) between solitary AFL patients with vs. without anticoagulation therapy.

Angiography with the 256-multislice spiral computed tomography and its application in evaluating atherosclerotic plaque and cerebral ischemia.

Ulceration of carotid arterial plaque is associated with cerebral events. Detection of ulcerated plaques will benefit patient from stroke and other ischemic events. The aim of this study was to evaluate morphology of atherosclerotic plaques in the carotid arteries and to assess its clinical impact in predicting cerebral events.A total of 386 patients were examined with 256-multislice spiral computed tomographic angiography (MSCTA).It was found that 356 of the 386 patients had cerebral ischemic symptoms. Spe...

Trichoblastic Carcinosarcoma of the Skin: A Case Report and Literature Review.

An 83-year-old man presented to the dermatology department for an ulcerated skin lesion of the back that had been increasing in size during the past 11 years. The physical examination revealed a well-defined, fleshy, reddish plaque measuring 10 × 20 cm in diameter with erosions and black areas on the surface. The patient underwent surgical excision with margins of 10 mm followed by a skin graft. Histologic section showed a lesion composed of 2 intimately intermingled epithelial and mesenchymal components a...

Dermoscopy of early non-ulcerated livedoid vasculopathy.

Livedoid vasculopathy is a rare disease related to a hypercoagulable state. It can lead to painful and chronic relapsing ulcerations. We report dermoscopic findings of early, non-ulcerated livedoid vasculopathy in five patients. A mixture of ivory-white atrophic areas with multiple erythematous papules in the center of the lesions is characteristic. With dermoscopy, these papules correspond to glomerular vessels. In the periphery of the lesions some telangiectatic linear vessels complete the picture, althou...

Clinical prediction of solitary pulmonary nodule after a curative resection for gastric cancer.

Gastric cancer metastasis to the lung can rarely manifest as solitary pulmonary nodule. The surgical strategies are different between metastasis from gastric cancer and primary lung cancer; therefore, the clinical prediction of solitary pulmonary nodule is important.

Solitary pigmented lesions in oral mucosa in Latin American children: A case series.

A variety of local and systemic processes caused exogenous and endogenous pigmentation of the oral mucosa. Solitary melanotic pigmentation is rare, hence the scarce number of studies in children and adolescents.

Atrophied Brain Lesion Volume: A New Imaging Biomarker in Multiple Sclerosis.

Lesion accrual in multiple sclerosis (MS) is an important and clinically relevant measure, used extensively as an imaging trial endpoint. However, lesions may also shrink or disappear entirely due to atrophy. Although generally ignored or treated as a nuisance, this phenomenon may actually be an important stand-alone imaging biomarker. Therefore, we investigated the rate of brain lesion loss due to atrophy (atrophied lesion volume) in MS subtypes compared to baseline lesion volume and to new and enlarging l...

Ulcerated Necrobiosis Lipoidica.

A multi-institutional report of peri-operative and functional outcomes after robot-assisted partial nephrectomy in patients with a solitary kidney.

To evaluate peri- and post-operative outcomes after robotic partial nephrectomy (RPN) in patients with a solitary kidney. A multi-institutional database of 1868 patients was used to identify 35 patients with a solitary kidney who underwent RPN at six different centers from 2007 to 2016. Peri-operative outcomes were summarized with descriptive statistics. We assessed the change in eGFR over time with a linear mixed-effects model. Median operative time, ischemia time, and estimated blood loss were 172 min, 1...

Performance of FDG-PET/CT in solitary pulmonary nodule based on pre-test likelihood of malignancy: results from the ITALIAN retrospective multicenter trial.

The aim of this study was to determine the performance of F-FDG-PET/CT in patients with solitary pulmonary nodule (SPN), stratifying the risk according to the likelihood of pulmonary malignancy.

Solitary Breast Metastasis From Rhabdomyosarcoma Shown on FDG PET/CT.

Rhabdomyosarcoma rarely metastasizes to breast. A 15-year-old adolescent girl underwent FDG PET/CT scan for staging a newly diagnosed alveolar rhabdomyosarcoma. The images showed not only the abnormal activity in the region of the right maxillary sinus, consistent with the known primary tumor, but also an intense focal activity in the right breast. The right breast lesion was excised, and the pathological results showed alveolar rhabdomyosarcoma.
