OBJECTIVES: The goal of this study was to investigate the role of the ground-glass opacity (GGO) ratio in lung adenocarcinoma in predicting surgical outcomes. METHODS: Patients who underwent surgical resection for pulmonary adenocarcinoma between January 2004 and December 2013 were reviewed. The clinical data, imaging characteristics of nodules, surgical approaches and outcomes were analysed with a mean follow-up of 87 months. RESULTS: Of 789 enrolled patients, 267 cases were categorized as having a GGO ratio ≥0...

BACKGROUND: Parathyroid glands can mimic thyroid follicular lesions on fine-needle aspiration (FNA) cytology and can lead to unnecessary or incorrect surgery. Newer molecular panel tests using next-generation sequencing (NGS) include analysis of cell type-specific gene expression profiles such as parathyroid. The study aim is to determine the frequency and clinical implications of parathyroid tissue identification by molecular testing in cytologically indeterminate "thyroid" lesions...

PURPOSE: To assess the added value of intratumoral ancillary features to conventional enhancement pattern-based diagnosis of hepatocellular carcinoma (HCC) on gadoxetic acid-enhanced magnetic resonance imaging (MRI). MATERIALS AND METHODS: A total of 773 consecutive patients with surgically resected 773 primary hepatic tumors (699 HCCs, 63 intrahepatic cholangiocarcinomas, and 11 benign nodules) who underwent gadoxetic acid-enhanced MRI were retrospectively identified...

OBJECTIVE: Pulmonary mucormycosis is an aggressive opportunistic fungal infection. We set out to evaluate the CT and MRI features of pulmonary mucormycosis. MATERIALS AND METHODS: Through a search of the electronic medical record from 2007 to 2017, we identified 30 patients with definite or probable mucormycosis. Two radiologists reviewed the initial chest CT examinations for the presence of features including the "reverse halo" sign, large ground-glass halo, and peripheral lesion distribution...

Erythema elevatum diutinum (EED) is a rare, chronic small-vessel vasculitis that presents as firm, red, violaceous, or brown papules and nodules on the extensor surfaces of the limbs. Oral dapsone is considered first-line therapy for EED; in the current case report, a patient presenting with EED began dapsone treatment and symptoms subsided within two weeks. Seven months later, the patient became pregnant and stopped dapsone owing to her concerns with dapsone use during pregnancy, resulting in recurrence of EED symptoms...

Vemurafenib ha probado ser una herramienta útil en el tratamiento de melanoma metastásico con mutación BRAF-V600E. Los efectos adversos incluyen artralgias, fatiga y toxicidad cutánea, siendo infrecuente la paniculitis. Presentamos el caso de una paciente de 43 años con melanoma metastásico que desarrolla lesiones subcutáneas dolorosas en miembros inferiores y superiores, asociadas a clínica sistémica después de 2 semanas de inicio de tratamiento con Vemurafenib + Cobimetinib. La histología demostró paniculitis linfocitaria septal y lobulillar...

Kimura disease is a rare, benign, chronic, immune-mediated inflammatory disorder. We report a 46-year-old man who presented with a cutaneous nodule behind his left ear. Surgical removal of the growth confirmed the histological diagnosis of KD. There was no recurrence found after 3 years follow-up.

A 75-year-old man presented to the dermatology clinic with an asymptomatic lesion on his right plantar surface. The lesion had progressively grown for two months. Physical examination revealed an erythematous and slightly scaly nodule measuring 10x10 mm. Dermoscopy examination showed central diffuse erythema with small red globules. A punch-biopsy revealed a proliferation of irregularly branched small vessels with collapsed lumen, extending in an infiltrative pattern in the superficial and deep dermis. Although this is a rare location, a diagnosis of microvenular hemangioma was made...

Precalcaneal congenital fibrolipomatous hamartoma is a benign condition of infancy that is sometimes misdiagnosed due to lack of reports in the literature. Lesions usually present with painless, non-pruritic, skin colored bilateral, solitary, symmetric nodules located in the middle of the heels. The lesions gradually increase in size and then regress by the age of 2 to3 years old.

A 55-year-old man presented with a history of asymptomatic, bilateral, figurate dermatosis consisting of erythematous, annular, linear, andarciform, indurated nodules and plaques on the lateral walls of thorax, flanks, and hypogastrium. His medical history was positive for chronic hepatitis C. Skin biopsy was compatible with the diagnosisof interstitial granulomatous dermatitis. Additionalinvestigation revealed positive rheumatoid factor, antinuclear antibodies, and cryoglobulins. Thepatient started treatment with high-potency topical corticosteroid...

Eccrine spiradenoma (ES) typically presents as a solitary tender lesion. Multiple ES is a rare variant of ES and can present in a segmental, linear, blaschkoid, or zosteriform pattern. The etiology of multiple ES is unknown, but several theories have been suggested including a multipotent stem cell origin. We report the case of a 30-year-old woman with multiple painful ES in a zosteriform pattern on the mid-back and abdomen. Skin biopsy of a representative lesion demonstrated a circumscribed tumor nodule encapsulated by a fibrous capsule with diffuse dense basophilic proliferation located in the dermis...

Hidrocystomas are benign cysts that typically present as translucent, bluish dermal nodules on the face and are rarely > 1 cm in size. They are classically categorized as eccrine or apocrine based on histologic features. We present a rare case of a giant apocrine hidrocystoma of the trunk, demonstrating that, although a rare variant, apocrine hidrocystomas can present both off the head and neck, and can be significantly larger in size than previously reported.

Acquired fibrokeratomas are benign and uncommon lesions consisting of collagenous papules and nodules covered by hyperkeratotic epidermis. These tumors occur mainly on the fingers and toes and infrequently on the palms and soles. They may possibly be triggered by a reaction to a trauma and presents as small and solitary dome-shaped lesions with a collarete of slightly raised skin at the base. Several case reports have been published of this rare lesion, with only a few investigators describing lesions of the feet...

A 61-year-old immunosuppressed renal transplant patient with inflammatory bowel disease presented with tender pink nodules on the trunk and extremities. An initial biopsy was suggestive of metastatic Crohn disease, but after disease persistence, a second biopsy revealed disseminated Mycobacterium haemophilum. Atypical mycobacterial infections should be considered in immunosuppressed patients. This case highlights the complexities of diagnosing such infections in patients with an underlying granulomatous condition and the particular growth requirements of M...

Elastomas are connective tissue nevi or hamartomas. They may occur in isolation or can be associated with familial syndromes such as Buschke-Ollendorff syndrome. Elastomas typically present in childhood as small ivory papules or firm skin-colored nodules that can coalesce into larger yellow plaques. These lesions are typically distributed over the extremities, abdomen, and back. Herein, we report an unusual case of a renal transplant recipient who presented with an acquired subungual papule with associated koilonychia and distal nail plate dystrophy...

OBJECTIVE: To establish an experimental model of acute cerebral schistosomiasis japonica and explore the MRI manifestations of acute cerebral schistosomiasis. METHODS: Rabbits were divided into 3 groups with 10 rabbits in each group. The rabbits in the experimental group were directly injected with suspension fluid of Schistosoma japonicum eggs (0.9 mg, 1 ml) by the cranial drilling method, those in the negative control group were given saline (1 ml) by the same method above-mentioned, and those in the blank control group were not given any treatment...

OBJECTIVE: To analyze the clinical features of 6 patients with imported schistosomiasis mansoni, including the epidemic history, clinical manifestations, laboratory tests and therapeutic effect, so as to provide references for improving the levels of diagnosis and treatment of physicians. METHODS: The clinical data of 6 patients with imported schistosomiasis mansoni from January 2009 to July 2016 were collected and analyzed. RESULTS: All the 6 imported patients with schistosomiasis mansoni had a clear history of cercarial infested water exposure...
