A confusing case report of pulmonary langerhans cell histiocytosis and literature review.

Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease. From the insidious onset and nonspecific manifestations, it is difficult to diagnose PLCH. To help improve the diagnosis and therapy options of adult PLCH, we present this case report and literature review about a confusing case of PLCH. In this report, we present a 37-year-old male PLCH case that was negative for CD1a and S100 expression. Smoking cessation and use of prescribed Spiriva appeared to improve the patient's symptoms. To the best of our knowledge, this is the first reported case of PLCH in which improved symptoms wer

Skin manifestations associated with systemic diseases - Part I.

The skin demonstrates what is happening in the body in many diseases, as it reflects some internal processes on the surface. In this sense, skin as an organ, goes beyond its protective and barrier functions, as it provides clues for the identification of some systemic diseases. The dermatologist then raises diagnostic hypotheses for conditions related to all systems and refers them to the appropriate specialty. With easy access to examination by trained eyes and biopsies, the skin can present specific or non specific alterations on histopathology. In the first case this combination establishes

Primary Amyloidosis Unmasked by Gastric Biopsy: A Case Report.

Amyloidosis is a broad category of diseases characterized by the extracellular accumulation of misfolded fibrillar proteins, which disrupt organ architecture and causes cellular toxicity. This ultimately results in vascular compromise and progressive organ dysfunction. Despite advances in serum free light chain assays and imaging modalities, diagnostic delays persist due to the underestimation of early signs and the need for multidisciplinary correlation. Our case report highlights a unique case of a patient with systemic AL amyloidosis involving the gastrointestinal (GI) system, who initially

Interstitial Lung Disease and Pulmonary Fibrosis: A Practical Approach for General Medicine Physicians with Focus on the Medical History.

Interstitial lung disease (ILD) and pulmonary fibrosis comprise a wide array of inflammatory and fibrotic lung diseases which are often confusing to general medicine and pulmonary physicians alike. In addition to the myriad of clinical and radiologic nomenclature used in ILD, histopathologic descriptors may be particularly confusing, and are often extrapolated to radiologic imaging patterns which may further add to the confusion. We propose that rather than focusing on precise histologic findings, focus should be on identifying an accurate etiology of ILD through a comprehensive and detailed m

Grzybowski's Generalized Eruptive Keratoacanthomas in a Patient with Terminal Kidney Disease-An Unmet Medical Need Equally Ameliorated by Topical Imiquimod Cream and Lapacho Tea Wraps: A Case Report.

IntroductionDevelopment of singular keratoacanthoma (KA) is generally considered a benign condition as it has a tendency to regress spontaneously in spite of histological similarity to squamous cell carcinoma. Most KAs undergo excision to rule out differential diagnoses. Several alternative treatment modalities (keratinolytic, ablative, immunomodulating, antiproliferative, or targeted therapy) have been described in the past with varying success, underlining the therapeutic challenges associated with large or multiple lesions. Isomorphic response (Koebner phenomenon) may limit the efficacy of

Pre-Hematopoietic Stem Cell Transplantation Lung Computed Tomography as an Alternative to the Pulmonary Function Test during the COVID-19 Pandemic.

The pulmonary function test (PFT) is an important test for risk stratification before allogeneic transplantation (allo-HCT). However, it might be preferable to avoid PFT as much as possible in the recent era of coronavirus disease 2019 (COVID-19), because PFT requires forced expirations and might produce aerosols, increasing the risk of COVID-19 transmission. Therefore, we tried to predict normal PFT results before allo-HCT based on computed tomography (CT) findings. This study included 390 allo-HCT recipients at our center for whom lung CT images and PFT results before allo-HCT were available

MPO-ANCA-Associated Hypertrophic Pachymeningitis Mimicking IgG4-Related Disease: A Case Report and Literature Review.

Hypertrophic pachymeningitis (HP) is a rare and chronic clinical disease characterized by thickening of the dura mater, leading to persistent headache, cranial neuropathy, seizures, and other neurological symptoms. Immune-mediated causes, particularly antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis and IgG4-related disease (IgG4-RD), are among the most common etiologies. We report a case of a 54-year-old female with recurrent headache, blepharoptosis, hearing loss, and markedly elevated inflammatory markers. Blood tests, and serum levels of IgG4 were within normal ranges. Cont

IntroductionIn this study, we evaluated the use and the contribution of radiopharmaceuticals to the field of lung neoplasms imaging using positron emission tomography/computed tomography.MethodsWe conducted review of the current literature at PubMed/MEDLINE until February 2020. The search language was English.ResultsThe most widely used radiopharmaceuticals are the following:Experimental/pre-clinical approaches: (18)F-Misonidazole (18F-MISO) under clinical development, D(18)F-Fluoro-Methyl-Tyrosine (18F-FMT), 18F-FAMT (L-[3-18F] (18)F-Fluorothymidine (18F-FLT)), (18)F-Fluoro-Azomycin-Arabinosi

Pontine Tuberculoma Mimicking an Astrocytic Tumor: A Case Report.

Tuberculomas located in the brainstem are rare entities. This article presents a case study detailing the diagnosis and treatment process of a patient with a pontine tuberculoma, as well as a literature review of tuberculomas located in the pons. A 39-year-old male patient showed progressive quadriparesis and deficits in VII, XI, and XII cranial nerves. MRI image initially suggested a pontine astrocytoma. A second biopsy revealed the presence of acid-fast bacilli. Following six months of anti-tuberculous treatment, the patient showed successful recovery.

Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma.

Superior vena cava (SVC) syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable

Relapsing polychondritis: tracheobronchial involvement and differential diagnoses.

This review is describing the diagnostic and therapeutic approach to tracheobronchial involvement in relapsing polychondritis (RP), with a focus on differential diagnoses of inflammatory origin. RP is a systemic auto-immune disease that mainly affects cartilage structures, progressing through inflammatory flare-ups between phases of remission and ultimately leading to deformation of the involved cartilages. Besides the damage of auricular or nasal cartilage, tracheobronchial and cardiac involvement are the most severe, and can seriously alter the prognosis. Tracheobronchial lesions are assesse

Rituximab-Induced Interstitial Lung Disease: A Possible Underestimated Complication-A Systematic Review.

Background: Rituximab, a monoclonal antibody targeting CD20, has revolutionized the management of B-cell lymphoproliferative disorders and some immune conditions, significantly improving disease control and patient survival. Beyond its indisputable therapeutic benefits, rituximab can cause serious pulmonary adverse events, particularly interstitial lung disease (R-ILD). Diagnosing R-ILD is challenging due to nonspecific clinical and imagistic features, and its true incidence is possibly underestimated. Methods: We conducted a systematic review to synthesize current evidence on R-ILD, focusing

Pseudomonas bronchopulmonary infections in a palliative care setting.

Blood stream infections and pneumonia caused by Pseudomonas aeruginosa is associated with high mortality, especially in an immunocompromised host. A large section of the palliative care patient population has varied forms of compromised immunity due to advanced cancer or cancer treatment, organ failures, chronic autoimmune disorders, degenerative conditions, and acquired immunodeficiency syndrome. The lung is one of the most frequently involved organs in a variety of complications in an immunocompromised host and infection is the most common complication. P. aeruginosa is one of the most commo

Epidemiology, Clinical Data, and Management of Aseptic Abscess Syndrome: Review of Published Cases Outside France.

Aseptic abscess syndrome is a clinical entity that is being increasingly documented. Unfortunately, apart from the French registry, there are no other studies presenting collective data.

The Risk of Sarcoidosis Misdiagnosis and the Harmful Effect of Corticosteroids When the Disease Picture Is Incomplete.

Sarcoidosis is a complex granulomatous disease of unknown etiology. Due to the heterogeneity of the disease, the diagnosis remains challenging in many cases, often at the physician's discretion, requiring a thorough and complex investigation. Many other granulomatous diseases have the potential to mimic sarcoidosis, whether infectious, occupational, or autoimmune diseases and starting an unnecessary corticosteroid treatment can worsen the patient's prognosis, leading to side effects that can be harder to treat than the actual disease.
