RESUMEN

BACKGROUND: Podoconiosis is a skin Neglected Tropical Disease (skin NTD) that causes lymphoedema, and affects barefooted subsistence farmers in some tropical countries. The clinical presentation and histopathologic correlates of podoconiosis have been understudied. Here, we systematically document the clinical and histopathologic spectrum of podoconiosis. METHODS: This is a cross-sectional study in Durbete, Ethiopia from February 2018 to October 2019. Dermatologists performed a patient history, physical examination, filariasis test strip, and skin biopsy for histopathologic examination. The results were summarised and a descriptive statistical analysis and Wilcoxon rank sum test with continuity correction was done. RESULTS: We recruited 289 patients for the study, 178 (61.6%) had stage 1 or 2 podoconiosis, and 111(38.4%) stage 3 to 5 podoconiosis. 188 (64.1%) had a family history of podoconiosis. In 251 (86.9%) patients, both legs were affected by podoconiosis and in 38 (13.1%) only one leg was affected. 220 (77.5%) patients had warty lesions, 114 (39.4%) had nodules. The median number of episodes of Acute Dermato-Lymphangio-Adenitis (ADLA) reported by the patients in the last three months was 2 (interquartile range (IQR) 1-4). Increased episodes of ADLA were significantly associated with stage 3-5 podoconiosis (P = 0.002), while burning pain in the feet was more common in stage 1 or 2 podoconiosis. Stage 3-5 disease was histopathologically characterised by epidermal and dermal thickening, verrucous acanthosis, inflammatory cell infiltrates (predominantly lymphoplasmacytic), dilated and ectatic and a reduced number of lymphatic vessels, eccrine ductal hyperplasia, and sclerosis such as thickened collagen bundles. CONCLUSION: We provide a detailed description of the different clinical patterns, associated clinical findings and the histopathologic spectrum of podoconiosis at different stages of the disease. Our observations should serve as a guide to classifying patients with podoconiosis for prognostic assessment and treatment decision.

RESUMEN

BACKGROUND: In Ethiopia, severe lymphedema and acute dermato-lymphangio-adenitis (ADLA) of the legs as a consequence of podoconiosis affects approximately 1.5 million people. In some this condition may lead to woody-hard fibrotic nodules, which are resistant to conventional treatment. We present a series of patients who underwent surgical nodulectomy in a resource-limited setting and their outcome. METHODS: In two teaching hospitals, we offered surgical nodulectomies under local anaesthesia to patients with persisting significant fibrotic nodules due to podoconiosis. Excisions after nodulectomy were left to heal by secondary intention with compression bandaging. As outcome, we recorded time to re-epithelialization after surgery, change in number of ADLA episodes, change in quality of life measured with the Dermatology Quality of Live Index (DQLI) questionnaire, and recurrence rate one year after surgery. RESULTS: 37nodulectomy operations were performed on 21 patients. All wounds re-reepithelialised within 21 days (range 17-42). 4 patients developed clinically relevant wound infections. The DLQI values were significantly better six months after surgery than before surgery (P<0.0001). Also the number of ADLA episodes per three months was significantly lower six months after surgery than before surgery (P<0.0001). CONCLUSION: Nodulectomy in podoconiosis patients leads to a significant improvement in the quality of life with no serious complications, and we recommend this to be a standard procedure in resource-poor settings.

RESUMEN

Elephantiasis nostras verrucosa, a rare manifestation of Kaposis sarcoma, is a progressive cutaneous hypertrophy caused by chronic non-filarial lymphedema secondary to obstruction of the lymphatic system that can lead to severe disfigurement of parts of the body that have gravity-dependent blood flow, due to edema, fibrosis, and hyperkeratosis, especially lower extremities. Among the various conditions that can induce chronic lymphedema are tumors, trauma, radiotherapy, obesity, hypothyroidism, chronic venous stasis, and AIDS-related Kaposis sarcoma. Kaposis sarcoma is a vascular tumor associated with the presence of human gammaherpesvirus 8 that is predominantly cutaneous, locally aggressive, with metastasis, and is associated with the production of factors that favor inflammation, lymphatic obstruction, and lymphedema.

RESUMEN

Primary immunodeficiencies are inherited disorders, which may be revealed in the context of autoimmune hemolytic anemia (AIHA). We report the case of a girl presenting with an enterovirus-related AIHA. Despite being in complete remission for her anemia after treatment, the initial CD4/CD8 lymphopenia dramatically worsened with time. Its sole clinical presentation was generalized verrucosis. Cellular quantitative and functional immunodeficiency was evidenced but no known molecular defect was identified despite extensive workup. This unlabeled profound naive T-lymphopenia was cured by bone marrow transplantation. No similar case was ever described in the scientific literature. Patients with AIHA and/or generalized verrucosis should be screened for primary immunodeficiency, before initiating any immunomodulatory treatment.

RESUMEN

Scrotal elephantiasis is defined as an increase in the scrotal volume which can reach a very large size. This study involved O.H, a married man aged 70 years, father of 4 children, farmer, native of and resident in Agadir (south of Morocco). Symptoms started 7 years before when scrotal edema and then an edema in both feet and legs gradually increasing in volume occurred. Physical examination showed scrotal elephantiasis with a circumference measured 80 cm and elephantiasis in both legs and feet. Locoregional assessment was based on pelvic magnetic resonance imaging (MRI). The patient was scheduled for monoblock scrotal resection under spinal anesthesia with removal of all of the tissue affected by the lymphedema around the testicle which were covered using the remaining skin and of the penis which was skin grafted using thin skin. The treatment aimed to ensure penis function and to manage the disfiguration. Conservative treatment based on lymphovenous bypass surgery or on the dilation of lymph vessels is no longer performed. Treatment is based on surgery. Surgery is avoided when there are absolute contraindications.

RESUMEN

RATIONALE: Follicular occlusion triad (FOT) is an autosomal recessive inherited disease and no more than 3 variants of the triad have been reported. We give a report in which scrotal elephantiasis is a variant of FOT and further perform a literature review. PATIENT CONCERNS: A 41-year-old man came to us because of a large scrotal cyst and generalized skin lesions that had occurred over the past 10 years. The generalized skin lesions consisted of hidradenitis suppurativa on the perineum and back, acne conglobata in the armpit, and dissecting cellulitis of the scalp. He took antibiotics for a long time but achieved poor effect. Furthermore, he told his father and elder brother also manifested such skin lesions. DIAGNOSES: Magnetic resonance showed a mass in the left scrotum with clear boundaries. A routine blood test showed a high leukocyte level of 12 × 10/L and a hemoglobin content of 78 g/L. C-reactive-protein increased. Series of autoimmune antibody tests were negative. The postoperative pathologic findings showed that the mass was an epidermoid cyst, and hematoxylin and eosin staining showed hyperkeratosis of the skin as well as inflammatory and edematous changes. A diagnosis of a variant of FOT was made. INTERVENTIONS: We removed skin abscesses and lesioned the inner part with hydrogen peroxide. Then we performed an excision of the scrotal lesion. OUTCOME: The patient recovered well and had no evidence of recurrence at a 16-month follow-up. LESSONS: We reported a case in which scrotal elephantiasis was a variant of FOT and surgical intervention played an important role in secondary urologic diseases.

RESUMEN

Lymphedema has always been a neglected global health care problem. A central requirement for the development of any chronic disease is the clear use of public health definitions that can be used internationally to define populations. The term "lymphedema" has historically been defined as either primary, resulting from failure of lymphatic development, or secondary, following damage to the lymphatics (e.g., cancer treatment, injury, or filariasis). Attempts to integrate causes of edema arising from damage to the venous system or the effects of gravity, immobility, and systemic disease have rarely been integrated. More recently, the prominent role of the lymphatics in tissue fluid homeostasis in all forms of chronic edema has been recognized. These advances led to the development of the term: "Chronic edema: a broad term used to describe edema, which has been present for more than three months." It can be considered an umbrella term that includes not only conventional "lymphedema" but also chronic swelling, which may have a more complex cause. This definition has been adapted in the international epidemiology study (LIMPRINT) that identified people throughout the health and social care systems in participating countries. Clearer definitions will allow for examination of this important public health problem that is likely to escalate given the projections of an aging population with multiple comorbidities. It will be possible to define both the hidden mortality and morbidity associated with complications, such as cellulitis and the impact on health-related quality of life. This evidence is urgently required to lobby for increased resource and effective health care in an increasingly competitive health care arena in which more established conditions have greater priority and funding.

RESUMEN

Elephantiasis nostras verrucosa is a progressively debilitating and disfiguring disease commonly presenting with verrucous, cobblestone-like papules, nodules, or plaques with nonpitting edema in the lower extremities. Histopathology is marked by hyperkeratosis and dermal or subcutaneous fibrosis as a result of chronic lymphedema. Risk factors include obesity, recurrent cellulitis, chronic venous insufficiency, congestive heart failure, scleroderma, radiation, trauma, and tumors. We report a 72-year-old man who presented to the dermatology clinic for an 11-year history of edematous legs, occasionally associated with ulcerations. The findings developed within a year of intrapelvic non-Hodgkin lymphoma and progressed gradually over 10 years after lymphoma remission. Physical examination revealed atypical features including compressible cysts and pitting edema extending from the lower legs to the thighs bilaterally. The patient was noncompliant for the recommended compressive devices and the condition progressively worsened over the course of 7 months of follow-up. Early interdisciplinary management using compressive devices and a lymphatic pump are recommended. Underlying causative factors should be assessed with regular follow-up to optimize treatment outcomes.

RESUMEN

BACKGROUND AND OBJECTIVE: Elephantiasis nostras verrucosa (ENV) is a disfiguring skin condition that is difficult to treat. Existing treatment modalities serve to improve cosmesis or treat symptoms. Herein, we report a case of ENV with lymphocutaneous fistula successfully treated with ablative carbon dioxide laser. STUDY DESIGN/PATIENTS AND METHODS: A 57-year-old woman with biopsy-proven ENV with lymphocutaneous fistula was treated with ablative carbon dioxide laser to the symptomatic area of her right thigh in 3 treatment sessions over 6 months. RESULTS: The patient had resolution of lymphocutaneous drainage as well as 90% improvement in the appearance of ENV lesions at the 1-month follow-up visit. CONCLUSION: Ablative carbon dioxide laser may provide cosmetic, symptomatic, and medical benefit for patients with localized ENV.

RESUMEN

We reported a case of a 49-year-old man who had chronic lymphoedema of bilateral lower limbs for 30 years, but he did not seek treatment. His disease was complicated with irreversible changes of elephantiasis nostras verrucosa and had recurrent admissions due to infection. He was not keen for surgical intervention. This case report illustrated a rare and non-reversible complication of a common skin disease, lymphoedema and also the importance of identifying and treating it early.

RESUMEN

BACKGROUND: Podoconiosis, non-filarial elephantiasis, is a non-infectious disease found in tropical regions such as Ethiopia, localized in highland areas with volcanic soils cultivated by barefoot subsistence farmers. It is thought that soil particles can pass through the soles of the feet and taken up by the lymphatic system, leading to the characteristic chronic oedema of the lower legs that becomes disfiguring and disabling over time. METHODS: The close association of the disease with volcanic soils led us to investigate the characteristics of soil samples in an endemic area in Ethiopia to identify the potential causal constituents. We used the in vitro haemolysis assay and compared haemolytic activity (HA) with soil samples collected in a non-endemic region of the same area in Ethiopia. We included soil samples that had been previously characterized, in addition we present other data describing the characteristics of the soil and include pure phase mineral standards as comparisons. RESULTS: The bulk chemical composition of the soils were statistically significantly different between the podoconiosis-endemic and non-endemic areas, with the exception of CaO and Cr. Likewise, the soil mineralogy was statistically significant for iron oxide, feldspars, mica and chlorite. Smectite and kaolinite clays were widely present and elicited a strong HA, as did quartz, in comparison to other mineral phases tested, although no strong difference was found in HA between soils from the two areas. The relationship was further investigated with principle component analysis (PCA), which showed that a combination of an increase in Y, Zr and Al2O3, and a concurrent increase Fe2O3, TiO2, MnO and Ba in the soils increased HA. CONCLUSION: The mineralogy and chemistry of the soils influenced the HA, although the interplay between the components is complex. Further research should consider the variable biopersistance, hygroscopicity and hardness of the minerals and further characterize the nano-scale particles.
