Pruritus and Cutaneous Lesions: Granuloma Annulare vs. Mycosis Fungoides in a Pa-tient with Comorbidities. Case Report

Introduction: Pruritus is a common symptom in dermatological practice. Affecting patients with a wide range of cutaneous and systemic diseases. It can be caused by cutaneous disorders, systemic diseases, neurological disorders, psychological disorders, medications, among others. When assessing individuals with pruritus and cutaneous lesions, it is essential to consider mycosis fungoides and granuloma annulare as noteworthy differential diagnoses. Case presentation: A 51-year-old female patient exhibited symptoms of pruritus and two occurrences of pruritic skin lesions. Accompanied by a low-grade fever measuring 37.7 ºC, as well as asthenia and myalgia. Physical examination revealed two rounded plaques with erythematous borders and multiple non-confluent papular lesions. Discussion: Differentiating between mycosis fungoides and granuloma annulare can be challenging due to the similarities in their clinical presentations. However, performing a biopsy is essential to reach a definitive diagnosis.Conclusions: A biopsy is being suggested for the front part of the left lower limb. The application of mometasone furoate twice a day for two weeks was prescribed. Subsequently, a meeting has been arranged to conduct a review and to carefully analyze the biopsy findings within thirty days.

Introducción: El prurito es un síntoma frecuente en la práctica dermatológica, que afecta a pacientes con una amplia gama de enfermedades cutáneas y sistémicas. Puede estar causado por trastornos cutáneos, enfermedades sistémicas, trastornos neurológicos, trastornos psicológicos y medicamentos, entre otros. En la evaluación de personas con prurito y lesiones cutáneas, es fundamental tener en cuenta la micosis fungoide y el granuloma anular como diagnósticos diferenciales destacables. Presentación del caso clínico: Una paciente de 51 años de edad presentaba síntomas de prurito y dos apariciones de lesiones cutáneas pruriginosas, acompañadas de fiebre baja de 37.7 ºC, así como astenia y mialgias. El examen físico reveló dos placas redondeadas con bordes eritematosos y múltiples lesiones papulares no confluentes. Discusión: Diferenciar entre micosis fungoide y granuloma anular puede ser un reto debido a las similitudes en sus presentaciones clínicas. Sin embargo, la realización de una biopsia es esencial para llegar a un diagnóstico definitivo. Conclusiones:Se sugiere la realización de una biopsia en la parte anterior del miembro inferior izquierdo. Se prescribe la aplicación de furoato de mometasona dos veces al día durante dos semanas. Posteriormente, se ha concertado una reunión para realizar una revisión y deliberar sobre los resultados de la biopsia en un plazo de treinta días

Granuloma anular maculoso / Patch granuloma annulare

El granuloma anular maculoso es una variante rara de granuloma anular, que representa un desafío diagnóstico. Su incidencia se desconoce y se presenta con mayor frecuencia en las mujeres de entre 40 y 70 años. Se asocia a las mismas entidades y responde a los mismos tratamientos que las otras variantes clínicas de granuloma anular. Se presentan los casos de 5 mujeres con diagnóstico de granuloma anular maculoso, que recibieron diferentes tratamientos tópicos y sistémicos, con respuestas clínicas variables.

Patch-type granuloma annulare is a rare variant of granuloma annulare, thus which represents diagnostic challenge. It has an unknown incidence and occurs most often in women between 40 and 70 years of age. It presents similar associations and responds to treatment as the clinical variants. We present 5 emale patients with patch-type granuloma annulare, who received different topical and systemic treatments, with variable clinical responses.

Generalized granuloma annulare after pneumococcal vaccination

Abstract Granuloma annulare may be caused by multiple triggers. Among these are vaccinations, which have been described as an infrequent cause of granuloma annulare. The authors report the first case of generalized granuloma annulare associated with pneumococcal vaccination in a 57-year-old woman, who presented cutaneous lesions 12 days after vaccination.

Interstitial mycosis fungoides / Micose fungoide intersticial

ABSTRACT Interstitial mycosis fungoides (IMF) is a rare variant of mycosis fungoides, a cutaneous T-cell non-Hodgkin's lymphoma. It is characterized by an interstitial dermal infiltrate of lymphocytes and histiocytes between collagen bundles. We report the case of a 54-year-old patient with pruritic hypochromic macules on the arms and forearms diagnosed with IMF. Special attention was given to the anatomopathological features that differentiate this entity from its differential diagnoses, such as inflammatory morphea, interstitial annular granuloma, and other variants of the mycosis fungoides itself. We also present a review of the literature on the classification of the IMF.

RESUMEN La micosis fungoide intersticial (MFI) es una variante poco común de la micosis fungoide, un linfoma cutáneo de células T no Hodgkin. Se caracteriza por un infiltrado dérmico intersticial de linfocitos e histiocitos entre haces de colágeno. Presentamos el caso de un paciente de 54 años con máculas hipocrómicas pruriginosas en brazos y antebrazos diagnosticado de MFI. Se prestó especial atención a las características anatomopatológicas que diferencian a esta entidad de sus diagnósticos diferenciales, como morfea inflamatoria, granuloma anular intersticial y otras variantes de la propia micosis fungoide. También presentamos una revisión de la literatura sobre la clasificación de la MFI.

RESUMO A micose fungoide intersticial (MFI) é uma variante rara da micose fungoide, um linfoma cutâneo de células T não Hodgkin. É caracterizada por um infiltrado dérmico intersticial de linfócitos e histiócitos entre feixes de colágeno. Relatamos o caso de um paciente de 54 anos com máculas hipocrômicas pruriginosas nos braços e antebraços com diagnóstico de MFI. Atenção especial foi dada às características anatomopatológicas que diferenciam essa entidade de seus diagnósticos diferenciais, como morfeia inflamatória, granuloma anular intersticial e outras variantes da própria micose fungoide. Apresentamos também uma revisão da literatura sobre a classificação da MFI.

Granuloma anular perforante: patologia inusual / Perforating Granuloma Annulare: unusual pathology

Resumen El Granuloma Anular (GA) es una dermatosis inflamatoria crónica, benigna, auto limitada, de etiología desconocida. Existen numerosas variantes clínicas dentro de las cuales se encuentra la perforante, de presentación inusual. La histopatología más característica de GA, cuenta con la presencia de histiocitos epitelioides en empalizada alrededor de áreas de degeneración focal de fibras de colágeno con depósitos de mucina. La variedad perforante evidencia eliminación transepidérmica de fibras de colágeno. Se presenta un paciente de 72 años de edad, diabético, dislipémico, con lesiones pruriginosas en dorso de ambas manos, con el diagnóstico de granuloma anular perforante. Realizó tratamiento con clobetasol tópico, más antihistamínicos por vía oral, quedando una cicatriz atrófica.

Abstract Granuloma annulare is a chronic, benign, self-limiting, inflammatory dermatosis of unknown etiology. There are numerous clinical variants within which is the perforating, unusual presentation. The most histopathology characteristic of GA is the presence of palisading epithelioid histiocytes around areas of focal degeneration of collagen with mucin deposits. The perforating variety evidences transepidermal elimination of collagen tissue. A 72 years-old, diabetes, dyslipidemic patient is presented with pruritic lessions on the dorsum of both hands, with the diagnosis of perforating granuloma annulare. I perform medical treatment with topical clobetasol, leaving an atrophic scar.

Granuloma anular atípico ¿sólo una patología benigna? / Atypical granuloma annulare¿only a benign entity?

RESUMEN El granuloma anular (GA) es una dermatosis inflamatoria crónica de carácter benigno, asintomática y autolimitada. Aún permanece desconocida la fisiopatología de dicha entidad, pero se ha sugerido una base inmunológica. Dicha dermatosis se caracteriza, en su forma clásica, por presentar pápulas que confluyen formando placas, de periferia elevada y centro deprimido, endisposición anular. Las lesiones son de color piel normal, ligeramente eritematosas o violáceas. Se describen diversas formas clínicas. Los cuatro tipos más frecuentes son: GA localizado, GA generalizado, GA perforante y GA profundo, subcutáneo o nodular. La clínica por sí sola, habitualmente, no presenta ningún desafío diagnóstico, ya que suele ser característica en la mayoría de los casos, peroen el caso de las formas clínicas atípicas es necesaria la confirmación con un estudio histopatológico. Se presenta el caso de un paciente masculino de 41 años de edad con dermatosis compatible con una forma atípica de GA.

ABSTRACT Granuloma annulare is a benign cutaneous inflammatory disease. It is usually asymptomatic and self-limited. While the exact pathophysiology is unknown, it has been associated with a retarded hypersensitivity of type IV driven by the presence of unspecified antigens. Classical cutaneous lesions are characterized by the presence of papules coalescing to form annular plaques with a central clearing or a central depression.The clinical manifestations vary from a usual localized form to a generalized one, both with erythematous, violaceous or skin-colored lesions. Given that most cases present the classical form, they do not pose a diagnostic challenge. However, histopathological study is necessary in the case of atypical clinical presentations. A 41-year-old male presented with a 4-month dermatosis. The physical examination showed four 2cm erythematous plaques, slightly infiltrated in the right upper limb and three lesions of 1cm in the left upper limb with the same characteristics. Tactile, pain and thermal sensitivity was conserved. The patient only referred to an occasionally mild pruritus.

Coexistence of morphea and granuloma annulare: a rare case report

ABSTRACT CONTEXT: Localized scleroderma (morphea) is characterized by fibrosis of skin and subcutaneous tissue. Granuloma annulare is a relatively common disease that is characterized by dermal papules and arciform plaques. CASE REPORT: Here, we present the case of a 42-year-old woman who developed granuloma annulare on the dorsum of her feet and abdominal region, and morphea on the anterior side of her lower limbs. We also discuss the etiological and pathogenetic processes that may cause the rare coexistence of these two diseases. CONCLUSION: Only a few cases in the literature have described coexistence of morphea and granuloma annulare.

Granuloma annulare on the palms in an elderly patient

Abstract: Granuloma annulare is a relatively common, idiopathic, benign inflammatory dermatosis, with a varied clinical presentation that often makes diagnosis difficult. It mainly affects the extremities, such as the dorsa of the hands and feet, forearms and legs. Palmar and plantar regions are generally spared. It occurs mainly in young female patients. The presentation of the palmar variant in an elderly patient is a rarity.

Perforating Granuloma Annulare Mimicking Papulonecrotic Tuberculid

Perforating granuloma annulare (PGA), a rare variant of granuloma annulare, is characterized by transepidermal elimination of altered collagen that clinically manifests an umbilicated papule with a central crust. It can be confused with papulonecrotic tuberculid (PNT) because of their similar appearance. Unlike PGA, PNT is usually related to tuberculosis infection with a typical histologic finding of wedge-shaped dermal necrosis. Here, we report the first Korean case of PGA mimicking PNT both clinically and histologically. A 43-year-old Korean woman presented with erythematous papules localized on the extensor surface of her limbs for one year. Some of these papules had a central umbilication or a crust. Regarding comorbidity, she had latent tuberculosis diagnosed with QuantiFERON®-TB Gold test about five months ago. She was on antituberculous medication. Initially, a diagnosis of papulonecrotic tuberculid accompanied by latent tuberculosis was considered. However, despite taking the antituberculous medication for five months, her skin lesions were not improved. Biopsy specimen from her arm lesion showed wedge-shaped area of necrosis in the dermis. Additionally, there were multiple focal mucin depositions and palisading granulomatous inflammation throughout the dermis. A diagnosis of PGA was made and she was treated with topical corticosteroid. After two weeks of applying topical corticosteroid, most of her skin lesions disappeared, leaving some hyperpigmented scars.

Three Cases of Generalized Granuloma Annulare Successfully Treated with Methotrexate / 대한피부과학회지

Granuloma annulare is a benign granulomatous skin disease, clinically characterized by dermal papules tending to form annular shapes. Granuloma annulare is classified into localized, generalized, subcutaneous, and perforating types. Localized granuloma annulare is likely to resolve spontaneously, while generalized granuloma annulare usually takes a chronic course. Topical steroids, phototherapy, isotretinoin, dapsone, hydroxychloroquine, and other various treatments have been proposed, but some cases have been resistant to all of those treatment modalities. We experienced 3 cases of generalized granuloma annulare demonstrating a recalcitrant course that were successfully treated with methotrexate and propose that methotrexate may be an effective option for recalcitrant generalized granuloma annulare treatment.

Case for diagnosis. Patch granuloma annulare

Abstract A 59-year-old woman reported a 20-day history of slightly scaly erythematous infiltrated patches on her palms and soles with a histopathological result which was consistent with interstitial-pattern granuloma annulare, clinically classified as patch granuloma annulare. This is a rare clinical variant of granuloma annulare, with an unknown incidence and characteristic clinical and histopathological features. The patient evolved with a complete remission of the lesions after biopsy and the use of high-potency topical corticosteroid.

Granuloma anular generalizado y enfermedad de Hansen. Presentación de un caso / Generalized Annular Granuloma and Hansen’s disease. Presentation of a Case

El granuloma anular es una dermatosis inflamatoria crónica, benigna, de etiología desconocida, generalmente autolimitada. En muchas ocasiones la lepra tuberculoide asemeja un granuloma anular y este siempre debe ser un diagnóstico diferencial a tener en cuenta. La relación entre el granuloma anular y la lepra aún no está muy clara, aunque pudiera estar relacionado con mecanismos inmunológicos desencadenados en el curso de ambas enfermedades. Por tales razones se presenta el caso de una paciente con manifestaciones cutáneas de ungranuloma anulargeneralizado, cuyo comienzo fue concomitante con el noveno mes de tratamiento para la enfermedad de Hansen (forma clínica tuberculoide). Las principales manifestaciones cutáneas que presentaba eran lesiones eritematosas, papulosas y anulares, de tamaños predominantemente pequeño, formando grandes placas, localizadas en cuello, región superior de la espalda y miembros. Se detectaron las alteraciones histológicas propias de la enfermedad, lo que corroboró el diagnóstico planteado. Se presenta el caso porque,en la literatura consultada, esta enfermedad no está descrita frecuentemente en asociación con la enfermedad de Hansen.

Annular Granuloma is benign chronic inflammatory dermatoses of unknown etiology, usually self-limited. In many cases tuberculoid leprosy resembles an Annular Granuloma and this should always be a differential diagnosis to be considered. The relationship between Annular Granuloma and Leprosy is not yet clear, although it may be related to immunological mechanisms triggered in the course of both diseases. For these reasons it is presented a case of a patient with cutaneous manifestations of annular generalized granuloma, whose onset was concomitant with the ninth month of treatment for Hansen’s disease (tuberculoid clinical form). The main cutaneous manifestations presented were erythematous, papular and annular lesions, predominantly small in size, forming large plaques, located in the neck, upper region of the back and limbs. Histological alterations of the disease were detected, which corroborated the diagnosis. The case is presented because, in the consulted literature, this disease is not frequently described in association with Hansen’s disease.

Patch-type granuloma annulare: a case report

Granuloma annulare (GA) is a benign, self-limited condition which the etiology remains unknown. It is clinically characterized as annularly, erythematous papules on the extremities. Histologically, it shows as palisading granulomas with central degenerated collagen and mucin deposits. The patient in this case report had a rare GA variant named patch-type GA. It appeared as asymptomatic erythematous macules with central clarification on the upper portion of thighs. Histopathology was compatible with interstitialtype GA. We highlight that a high index of suspicion is necessary to make the diagnosis of patch-type GA and confirmation can only be achieved through histopathology study. (AU)

O granuloma anular (GA) é uma condição benigna, autolimitada e de etiologia desconhecida. Clinicamente é caracterizado por pápulas eritematosas anulares nas extremidades. Do ponto de vista histológico, observa-se a formação de granulomas com colágeno degenerado em sua porção central e depósito de mucina. O paciente deste caso clínico foi diagnosticado com uma variante rara de granuloma anular, na sua forma macular. A lesão se apresentava como máculas eritematosas assintomáticas na porção superior das coxas. Nos cortes histológicos, o quadro era compatível com GA do tipo intersticial. Neste trabalho enfatiza-se a necessidade de um elevado índice de suspeição clínica para o diagnóstico de GA macular e a confirmação só poderá ser alcançada através do estudo histopatológico. (AU)

Granuloma annulare treated with narrowband UVB phototherapy

Abstract Granuloma annulare is a benign cutaneous inflammatory disease, whose lesions have spontaneous improvement in two years in 50% of cases, but there is recurrence in 40% of patients. Treatment may be topical, intralesional or systemic. The use of phototherapy with narrowband UVB is highlighted, whose mechanism of action in this disease is still unclear, probably related to the inhibition of T lymphocytes. Herein, a case of a disseminated granuloma annulare of difficult therapeutic management is described. It was treated with narrowband UVB phototherapy twice a week for six months, with good clinical improvement, being a good low-risk therapeutic option and that, in this case, provided quick and satisfactory response.

Granuloma anular subcutáneo: reporte de un caso / Subcutaneous granuloma annulare: a case report

El granuloma anular es una dermatosis inflamatoria granulomatosa de carácter benigno y autolimitado. El granuloma anular subcutáneo es una variante poco común, que se presenta casi exclusivamente en niños menores y se caracteriza por la aparición de nódulos de consistencia firme de predominio en extremidades inferiores, glúteos, manos y cuero cabelludo. OBJETIVO: Reportar un caso de granuloma anular subcutáneo, revisar su diagnóstico diferencial y las opciones terapéuticas actuales. CASO CLÍNICO: Paciente de sexo masculino de 4 años. Desde los 2 años y medio con nódulos subcutáneos indurados asintomáticos, inicialmente en dorso de dedo medio mano izquierda, luego en dorso de mano izquierda, primer ortejo derecho, zona frontal izquierda y cuero cabelludo. La biopsia excisional de algunas lesiones de cuero cabelludo fue compatible con granuloma anular subcutáneo. Como tratamiento se indicó clobetasol 0,05% crema 2 veces al día en lesiones por 1 mes, sin cambio en las lesiones. CONCLUSIONES: El granuloma anular subcutáneo debe considerarse dentro del diagnóstico diferencial de nódulos subcutáneos en niños. En la mayoría de los casos se requerirá biopsia y estudio histopatológico de las lesiones para su confirmación diagnóstica. Debido a su tendencia a la resolución espontánea, generalmente se sugiere no tratar y controlar periódicamente.

Granuloma annulare is a benign and self-limited cutaneous disease. Subcutaneous granuloma annulare is an uncommon variant seen almost exclusively in young children, characterized by firm nodules appearing more frequently in lower extremities, buttocks, hands and scalp. OBJECTIVE: To report a case of subcutaneous granuloma annulare and review its differential diagnoses and treatments. CLINICAL CASE: A 4 year-old male patient. Since 2 and a half years of age he presented asymptomatic firm subcutaneous nodules on the back of the left middle finger and later on the back of the left hand, right big toe, left frontal area and scalp. Excisional biopsy of some lesions from the scalp was consistent with subcutaneous granuloma annulare. Clobetasol 0,05% cream twice a day for 1 month was prescribed without response. CONCLUSIONS: Subcutaneous granuloma annulare must be considered within the differential diagnosis of subcutaneous nodules in children. In most of the cases a biopsy and histopathology of the lesions will be required to confirm the diagnosis. Due to its tendency to spontaneous resolution, treatment often is not necessary and periodic evaluation is recommended.

Granuloma Annulare Successfully Treated with a Combined Regimen of Excimer Laser and Topical Tacrolimus / 대한피부과학회지

Granuloma annulare is a relatively common benign dermatosis of unknown etiology. It is typically characterized by skin-colored to violaceous annular or arcuate lesions. The localized form of the disease usually resolves spontaneously, but treatment may be required in cases of intractable symptoms such as pruritus, or for cosmetic purposes. Herein, we report the case of a 65-year-old man diagnosed with a localized form of granuloma annulare that was refractory to various treatments but showed clinical improvement with a combined regimen of excimer laser and topical tacrolimus.

Monthly rifampicin, ofloxacin, and minocycline therapy for generalized and localized granuloma annulare.

Background: The localized form of granuloma annulare is usually self‑limiting, resolving within 2 years. Generalized granuloma annulare, on the other hand, runs a protracted course, with spontaneous resolution being rare. It is also characterized by a later age of onset, an increased incidence of diabetes mellitus, poor response to therapy, and an increased prevalence of HLA Bw35. Objective: To assess the efficacy of monthly pulsed rifampicin, ofloxacin, and minocycline (ROM) therapy in the management of granuloma annulare.Methods: Six biopsy proven patients of granuloma annulare were included in the study, five of the generalized variety, and one localized. Three of these patients were resistant to standard modalities of treatment. All six patients were treated with pulses of once monthly ROM till complete resolution of all lesions. Results were analyzed in terms of complete resolution of lesions and side effects. Presence of comorbid conditions was noted. Result: All six patients were successfully treated with 4-8 pulses of monthly ROM. None of the patients reported any adverse effects. Limitations: Small sample size and the lack of a control group are limitations. Conclusion: Treatment with pulses of once monthly ROM caused complete resolution of lesions in both localized and generalized granuloma annulare, even in cases recalcitrant to conventional therapy. There were no side effects in any of the patients. Larger trials are needed to substantiate the efficacy of monthly ROM in granuloma annulare.
