Limitations of Immunohistochemistry in Diagnosis of a Primary Mucinous Carcinoma of the Skin and Its Metastasis
2020
We describe the case of a 67-year-old female patient who presented with an unclear swelling on the right supraclavicular neck, two years after resection of a mucinous carcinoma on the right mastoid. Two pathological reports from separate universities diagnosed the primary mastoid skin lesion as a metastatic adenocarcinoma. Strikingly, GATA binding protein 3 (GATA3) and mammaglobin, both immunomarkers found in breast cancer, were positive. An urgent search for the primary tumor most likely in the breast was commenced. However, as no other primary tumor could be detected at that time, a Primary Mucinous Carcinoma of the Skin (PMCS) was also debated. Two years later neck node enlargement was s…
Sepsis due to Streptococcus pneumoniae associated with secondary hemophagocytic lymphohistiocytosis in a splenectomized patient for spherocytosis
2017
Abstract Rationale: Hemophagocytic lymphohistiocytosis (HLH) is a syndrome that is characterized by an inappropriate hyperinflammatory immune response – primary, as a consequence of a genetic defect of NK cells and cytotoxic T lymphocytes or – secondary, in the progression of infections, rheumatic or autoimmune diseases, malignancies or metabolic diseases. Patient concerns: We present the case of a secondary HLH due to Streptococcus pneumoniae infection in a splenectomised patient for spherocytosis, a 37-year-old patient who was splenectomised in childhood for spherocytosis, without immuneprophylaxis induced by antipneumococcal vaccine. Outcomes: He developed a severe pneumococcal sepsis as…
A case report of double etiology of ecthyma gangrenosum
2019
Abstract Rationale: Ecthyma gangrenosum is a cutaneous infection, most commonly occurring during sepsis evolution with Pseudomonas aeruginosa on an immunocompromised background. There have been rare case reports in previously healthy children and rarer are the cases with double etiology. Patient concerns: We present the case of a female Caucasian patient, aged 1 year and 8 months, who developed severe sepsis during flu evolution with predominant respiratory and cerebral manifestations. On admission, at skin level, there was noticed a necrotic coccygeal ulceration (with rapid increasing dimensions 0.5/0.5 cm in 24 hours), and with the transformation from a dry necrosis in a sphacelus at the …
Diagnostic challenges and potential early indicators of breast periprosthetic anaplastic large cell lymphoma
2020
Abstract Rationale: Anaplastic large T-cell lymphoma (BI-ALCL) is a rare primitive lymphoma described in women with breast implant prostheses, which has been arousing interest in recent years due to its potentially high social impact. The difficult diagnosis associated with the high and increasing number of prosthetic implants worldwide has led to hypothesize an underestimation of the real impact of the disease among prosthesis-bearing women. The aim of this work is to search for specific radiological signs of disease linked to the chronic inflammatory pathogenetic mechanism. Patient concerns: This work describes a case of BI-ALCL in an American woman with no personal or family history of c…
Pityriasis rosea Gibert triggered by SARS-CoV-2 infection: A case report.
2021
RATIONALE: Pityriasis rosea Gibert is an erythematous-papulosquamous dermatosis that frequently occurs in young adults. The etiopathogenesis of PR is still unknown, but is frequently associated with episodes of upper respiratory tract infections. It is likely that a new viral trigger of pityriasis rosea is the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). PATIENT CONCERNS: We present the case of a female patient in whom the diagnosis of pityriasis rosea led to the investigation and diagnosis of the SARS-CoV-2 infection. The patient presented to the Department of Dermatology for a 3âweek duration of an extremely pruritic erythematous-squamous lesion, initially on the trunk …
Viridans streptococcal infective endocarditis associated with fixed orthodontic appliance managed surgically by mitral valve plasty
2018
Abstract Rationale: Streptococcus viridans, a heterogeneous group of alpha-hemolytic streptococci, is part of the normal flora of the mouth, usually responsible for dental caries (Streptococcus mutans, Streptococcus sanguinis), and pericoronitis, as well as for subacute infective endocarditis. They are responsible for 40-60% of the endocarditis cases occurring on the normal valves, especially in male patients and over 45 years of age. A change in the bacterial flora of the oral cavity is taking part after orthodontic fixed appliances are introduced into the oral cavity, change that is associated with an increased concentration of the acidogenic bacteria. Bacteraemia is the consequence of or…
Ultrasound-guided percutaneous treatment of a calcific acromioclavicular joint
2020
Abstract Rationale: Calcific tendinopathy is one of the most frequent causes of nontraumatic shoulder pain. However, intra-articular calcifications appear to be an infrequent condition. We herein report a rare case study of an intra-articular calcification of the acromioclavicular joint. Patient concerns: A 46-year-old man presented with an acute pain in the anterior superior region of the left shoulder which also radiated to the left cervical region. The man during the physical evaluation also presented severe functional limitation of the shoulder movements in all planes of motion. Diagnoses: The diagnosis was carried out through a radiographic and an echotomographic examination, highlight…
Sobre alguns participis actius amb verbs de moviment
2021
L’objectiu d’aquest estudi és analitzar les estructures formades a partir de la combinació d’un participi amb un verb de moviment, en casos com venir plorat de casa. L’interès d’aquestes dades rau en el fet que els participis que descrivim no són actius (plorat, tossit), però adquireixen una lectura activa en combinar-se amb verbs de desplaçament (venir, sortir, arribar). Al llarg de l’article recopilem i descrivim les dades que segueixen aquesta configuració i mirem d’esbossar alguns apunts per a una possible anàlisi formal. D’una banda, seguint la proposta d’Armstrong (2017), defensem que verbs com plorar o tossir permeten la formació d’un participi actiu resultatiu perquè tenen un object…
