BACKGROUND: Lichen planopilaris (LPP) is a potential trichologic emergency that can result in permanent scarring alopecia. Histopathology is a key component of the diagnostic work-up. OBJECTIVE: To identify the key histologic features that…

Contrast-enhanced ultrasonography (CEUS) is an imaging modality that shows promise in the detection and characterization of renal masses, as well as treatment through CEUS-guided percutaneous radiofrequency ablation. These techniques may be…

OBJECTIVE: To discuss the diagnosis and management of metastatic renal cell carcinoma presenting as a parotid mass by studying such cases. STUDY DESIGN: Retrospective review. METHODS: Identification of 24 previously reported cases of renal cell…

Cases of primary colorectal signet-ring cell carcinoma metastatic to the tonsil are extremely rare. To the best of our knowledge, only 4 such cases have been previously reported in the literature. We report a new case in a 76-year-old white woman.…

Malignant peripheral nerve sheath tumors (MPNSTs) are rare soft tissue sarcomas that arise from peripheral nerve fibers and are derived from Schwann cells, perineural cells, or fibroblasts. MPNST is an aggressive neoplasm in which local recurrence is…

BACKGROUND: The value of routine frozen section examination for intraoperative diagnosis of thyroid cancer and determination of extent of thyroidectomy is controversial and needs to be evaluated on an institution to institution basis. METHODS: A…

PURPOSE: The purpose of this study was to evaluate whether ultrasonography is helpful in predicting malignancy in patients with a thyroid nodule and atypia/follicular lesion of undetermined significance (AFLUS). METHODS: All patients with a…

A case of a melanotic schwannoma presenting as a soft tissue mass of the abductors of the hip is reported. The radiographic findings suggested myositis ossificans, but several subtle findings raised the concern for something else. A bilobed…

We report a case of cutaneous vasculopathy associated with the use of levamisole-adulterated cocaine. This recently described clinical entity is characterized by a purpuric rash with a predilection for the ears, leukopenia, and anti-neutrophilic…

Hemolytic-uremic syndrome following quinine ingestion is a newly described phenomenon, with just two previous descriptions of 4 cases in the literature. We describe a 5th case. The reaction may be mediated by the presence of antibodies reactive…

Transbronchial lung biopsy (TBLB) is associated with pneumothorax, 12% occurring 1 to 4 hours postprocedure (delayed pneumothorax). We report a case of a delayed pneumothorax first diagnosed on a positron emission tomography (PET) scan performed 5…

We describe four families with a strong familial expression of Barrett's/gastroesophageal reflux disease (GERD) complex spanning one to four generations with two to seven affected members per family. The purpose of this report is to highlight genetic…

Purpose: To prospectively evaluate the performance of real-time ultrasonographic (US) shear-wave elastography (SWE) in the diagnosis of peripheral zone prostate cancer in patients with high and/or increasing prostate-specific antigen levels and/or…

There are multiple factors that affect the shear wave speed in the assessment of liver stiffness. In this case report, we present a case of hemochromatosis that has elevated liver stiffness suggestive of significant fibrosis or cirrhosis; however on…

We report a case of AFH presenting as an asymptomatic subcutaneous nodule on the arm of a 6-year-old boy. AFH is a fibrohistiocytic tumor of intermediate malignancy. Predominantly seen in children and young adults, AFH presents as a deep dermal or…

In some individuals, chronic lymphocytic leukemia (CLL) may be associated with glomerular disease from membranous nephropathy with resultant nephrotic syndrome. CLL is characterized by abnormal immunoregulation with a malignant clonal proliferation…
