Granulomatous slack skin: report of a case associated with Hodgkin's disease and a review of the literature.
1994
We report a case of granulomatous slack skin (GSS) associated with Hodgkin's disease, and review the literature on this entity. GSS, a variant of cutaneous T-cell lymphoma, clinically presents with erythematous patches in the flexures, which gradually transform into bulky, pendulous areas of skin. Histology shows an elastolytic granulomatous infiltrate, with atypical lymphoid cells, and occasional epidermotropism. As far as we are aware, 10 cases of GSS, including our patient, have been reported in detail. The male:female ratio of these cases is 9:1, and the age range 15-51 years. Five cases were associated with Hodgkin's disease, one with small lymphocytic lymphoma, and one developed cutan…
Characterization of the Microenvironment in Positive and Negative Sentinel Lymph Nodes from Melanoma Patients
2015
Melanomas are aggressive skin tumors characterized by high metastatic potential. Our previous results indicate that Natural Killer (NK) cells may control growth of melanoma. The main defect of blood NK cells was a decreased expression of activating NCR1/NKp46 receptor and a positive correlation of NKp46 expression with disease outcome in stage IV melanoma patients was found. In addition, in stage III melanoma patients, we identified a new subset of mature NK cells in macro-metastatic Lymph nodes (LN). In the present studies, we evaluated the numbers of NK cells infiltrating primary cutaneous melanoma and analyzed immune cell subsets in a series of sentinel lymph nodes (SLN). First, we show …
Epidemiology of desquamative gingivitis: evaluation of 125 patients and review of the literature
2009
Background Desquamative gingivitis (DG) is a descriptive term used to indicate epithelial desquamation, erythema, erosions, and/or vesiculobullous lesions of the gingiva. DG is commonly associated with several mucocutaneous disorders and systemic conditions that may carry a poor prognosis and high morbidity; however, there are no clear data concerning the frequency of these disease associations. Methods We investigated the epidemiologic features of DG in 125 patients and compared our findings with information from a literature review. Results In our series, 88% of patients with DG had one of the following three disorders: oral lichen planus (OLP), mucous membrane pemphigoid (MMP), or pem…
CXCR3 chemokine receptor immunoreactivity in primary cutaneous malignant melanoma: correlation with clinicopathological prognostic factors.
2007
A role for CXCR3, the receptor for chemokines Mig, IP-10 and interferon-inducible T cell alpha-chemoattractant, in tumour cell migration during melanoma progression has been proposed.To analyse CXCR3 expression in primary cutaneous malignant melanomas and its comparison with clinicopathological and prognostic factors.A retrospective immunohistochemical study was carried out on formalin-fixed paraffin-wax-embedded sections from 82 patients with primary invasive cutaneous melanomas, with a monoclonal antibody to CXCR3 (clone 49801.111; RD Systems). Immunoreactivity was semiquantitatively evaluated: labelling intensity (0, absent; 1, weak; 2, moderate; 3, strong) multiplied by the percentage o…
Cutaneous Lymphadenoma Is a Distinct Trichoblastoma-like Lymphoepithelial Tumor With Diffuse Androgen Receptor Immunoreactivity, Notch1 Ligand in Ree…
2021
The term "cutaneous lymphadenoma" was coined in this journal for an unusual lymphoepithelial cutaneous adnexal neoplasm, possibly with immature pilosebaceous differentiation. Some authors further proposed that cutaneous lymphadenoma was an adamantinoid trichoblastoma. However, although a hair follicle differentiation is widely accepted, the fact that this is a lymphoepithelial tumor is not appropriately explained by the trichoblastoma hypothesis. Our goal was to further clarify the phenotypic and genotypic features of cutaneous lymphadenoma in a series of 11 cases. Histologically, a lobular architecture surrounded by a dense fibrous stroma was present in all cases. The lobules were composed…
Long-term outcomes with subcutaneous C1-inhibitor replacement therapy for prevention of hereditary angioedema attacks
2019
Background For the prevention of attacks of hereditary angioedema (HAE), the efficacy and safety of subcutaneous human C1-esterase inhibitor (C1-INH[SC]; HAEGARDA, CSL Behring) was established in the 16-week Clinical Study for Optimal Management of Preventing Angioedema with Low-Volume Subcutaneous C1-Inhibitor Replacement Therapy (COMPACT). Objective To assess the long-term safety, occurrence of angioedema attacks, and use of rescue medication with C1-INH(SC). Methods Open-label, randomized, parallel-arm extension of COMPACT across 11 countries. Patients with frequent angioedema attacks, either study treatment-naive or who had completed COMPACT, were randomly assigned (1:1) to 40 IU/kg or …
Interdigital syphilis: a rare form of secondary syphilis
2019
A 39-year-old man with bilateral painful erosions in his toe web spaces and on the penile shaft was misdiagnosed as having Gram-negative toe web infection, and treated with broad-spectrum oral antibiotics. Further evaluation revealed positive serological tests for syphilis. Pedal interdigital syphilis is a rare manifestation of secondary syphilis.
Randomized, double-blind study comparing percutaneous electrolysis and dry needling for the management of temporomandibular myofascial pain
2018
Background To assess whether the techniques of percutaneous needle electrolysis (PNE) and deep dry needling (DDN) used on trigger points (TrP) of lateral pterygoid muscle (LPM) can significantly reduce pain and improve function in patients with myofascial pain syndrome (MPS) compared to a control group treated with a sham needling procedure (SNP). Material and Methods Sixty patients diagnosed with MPS in the LPM were selected and randomly assigned to one of three groups. The PNE group received electrolysis to the LPM via transcutaneous puncture. The DDN group received a deep puncture to the TrP without the introduction of any substance. In the SNP group, pressure was applied to the skin wit…
Experimental Percutaneous Cannulation of the Supraorbital Arteries: Implication for Future Therapy
2005
Purpose There is some evidence to suggest that thrombolysis has a beneficial effect in retinal vessel occlusion. However, there is concern that this therapeutic approach carries the risk of hemorrhage. Retrograde cannulation of the supraorbital arteries followed by irrigation with fibrinolytic agents may have the potential to minimize the risk of major complications. The study was conducted to investigate the anatomic and sonographic features of the supraorbital arteries. Methods This cadaver dissection study was performed on the orbits of 12 cadaveric specimens. In each orbit, the supraorbital region was dissected, followed by cannulation of the supraorbital vessels and injection of ink. I…
Monitoring free serum IgE in severe asthma patients treated with omalizumab
2012
SummaryBackgroundBenefit of treatment with the monoclonal anti-IgE-antibody omalizumab in severe IgE-dependent asthma requires a significant reduction of serum free IgE concentrations. It is unclear if monitoring free serum IgE is clinically meaningful once omalizumab treatment is initiated.MethodsFree IgE and omalizumab serum concentrations were quantified in 22 patients with severe asthma (68% female, 47 ± 11 yrs, mean (±SD) pre-bronchodilator FEV1 62 ± 13%, baseline mean (±SEM) free serum IgE 652 ± 136 ng/ml) treated with omalizumab for 4 months using a Recovery-ELISA.ResultsOmalizumab treatment reduced free serum IgE prior to the second omalizumab injection by 73%, after 16 weeks by 81%…
