Granuloma annulare (GA) is a fairly common inflammatory skin condition with a range of clinical subtypes. We describe an unusual case of unilateral GA confined to the thigh on a previously amputated limb. A man in his 80s with a past medical history of below-knee amputation of the left leg owing to severe leg ulcers from pyoderma gangrenosum, chronic lymphocytic leukemia, and dyslipidemia developed a slowly spreading eruption on the distal stump spreading proximally.

Although granuloma annulare (GA) is a relatively common dermatologic condition, little is known about its epidemiology and pathogenesis. Additionally, there is conflicting evidence regarding its association with other diseases. In our retrospective study, we attempted to determine the number of cases of GA seen annually at a large academic center and clarify disease associations with GA. Read More

Background: The full-blown lesion of granuloma annulare (GA) is characterized by necrobiotic granulomas with palisading of histiocytes and stromal mucin deposition. Cases in which the granulomatous features are not fully developed have been described as the "interstitial" variant; however, there is no good definition regarding their criteria for diagnosis.

Methods: We conducted a retrospective study of 97 cases of GA. Read More

Granuloma annulare is a benign inflammatory skin disease potentially related to a delayed hypersensitivity reaction to the dermis. Generalized granuloma annulare (GGA) manifests as diffuse skin-colored to erythematous annular or nummular plaques affecting at least the trunk and either upper or lower extremities, or both. GGA is resistant to many therapeutic modalities, making it difficult to treat. Read More

Granuloma annulare (GA) is a benign, self-limited skin disease of unknown etiology characterized by annular, flesh-colored to erythematous grouped papules or plaques. Lesions of GA are typically located on the lateral or dorsal surfaces of the hands and feet, arms, thighs, and trunk. We present the case of a patient with GA who presented with erythematous, annular plaques localized to the bilateral inguinal folds, mimicking tinea cruris. Read More

Cutaneous mucinosis of infancy (CMI) is a rare dermatologic condition, first reported in 1980 and currently classified within the complex group of papular mucinoses. We report a case of CMI and review the prior 13 cases in the literature. The patient was a 5-year-old girl who presented with asymptomatic dermal papules and plaques on her leg and back with no overlying color change. Read More

Background: Granuloma annulare (GA), a benign inflammatory skin disease, is considered a Th1-type delayed hypersensitivity reaction. Localized GA is likely to resolve spontaneously, whereas disseminated GA (DGA) may persist for decades and can be resistant to treatment. Biologics including TNF-α inhibitors have been proposed and utilized as salvage therapy for GA and other related diseases, interstitial granulomatous dermatitis (IGD), and actinic granuloma (AG).

We report the case of an 80-year-old man with generalized granuloma annulare (GGA) who subsequently developed giant cell arteritis (GCA). Steroid treatment was effective for both diseases in this case. Although cases of concomitant GGA and GCA have rarely been reported, previous studies suggest that common histological characteristics underlie the two diseases. Read More

Granuloma annulare (GA) is the most common non-infectious disease. Despite the fact that it is a benign disease, it can be associated with a variety of disorders and certain drugs including biological disease-modifying anti-rheumatic drugs (bDMARDs). A 50-year-old man with a history of rheumatoid arthritis refractory to methotrexate, hydroxychloroquine and infliximab was treated with tocilizumab (TCZ), an interleukin-6 receptor antagonist, 162 mg subcutaneously every week.

It mainly affects the extremities, such as the dorsa of the hands and feet, forearms and legs. Palmar and plantar regions are generally spared. Read More

Inflammatory granulomatous dermatitides include cutaneous sarcoidosis, necrobiosis lipoidica, granuloma annulare, and reactive granulomatous dermatitis. The etiopathogenesis of these disorders is not well understood; but the T helper 1 response mediated by interferon-gamma, tumor necrosis factor-alpha, and interleukin (IL) 1, 2, and 6 and the T helper 17 response mediated by IL-17 play a role. These inflammatory granulomatous disorders often have cutaneous manifestations in addition to extracutaneous manifestations or associations with systemic diseases. Read More

Granuloma multiforme (GM) is a chronic granulomatous skin condition which is clinically characterised by annular lesions mainly over sun-exposed areas and histologically by focal necrobiosis and histiocytic granulomas. Its significance lies in the fact that it can clinically resemble tuberculoid leprosy and hence it can be missed. Here, we report a case of GM from India in a 55-year-old female agriculturist, with multiple asymptomatic large annular rings of papules over the photo-distributed areas. Read More

Cutaneous granulomas without detectable infectious etiology rarely occur in children and adults with primary immunodeficiency disorders. These cutaneous granulomas are primarily seen in combined variable immunodeficiency, ataxia-telangiectasia, and severe combined immunodeficiency (SCID) and can emulate the reaction patterns seen in sarcoidosis and granuloma annulare. To date, the literature has described only six cases of non-infectious cutaneous granulomas in SCID. Read More

Although diagnosis of cutaneous granulomatous disorders (CGDs) is usually suspected based on morphologic findings, localization, and anamnestic data, clinical differentiation from each other and from similar dermatoses may be challenging. Recently, dermatoscopy has been demonstrated to be a useful tool for assisting the recognition of several CGDs. This article provides a current overview of the dermatoscopic features of the main noninfectious and infectious CGDs, including sarcoidosis, necrobiosis lipoidica, granuloma annulare, rheumatoid nodules, and leishmaniasis.

Immune checkpoint inhibitors (ICPIs) have emerged as a frontline treatment for a growing list of malignancies. Disruption of the negative regulatory immune checkpoints by ICPIs has been associated with many immune-related adverse events. Granulomatous reactions, such as sarcoidosis-like reactions, granulomatous panniculitis, granuloma annulare, and granulomatous dermatitis, are uncommon but increasingly recognized immune-related adverse events seen in patients treated with ICPIs.

Dear Editor, Subcutaneous granuloma annulare (SGA) is considered a rare clinical variant of granuloma annulare, a common self-healing chronic inflammatory disorder that may appear in childhood as well as in adult age (1-3). A 29-year-old female patient reported the onset of several small subcutaneous nodules on the dorsal aspect of the second interphalangeal joint of the left medius finger and the left elbow, accompanied by vague joint pain, had occurred 13 years ago. Specific markers for rheumatoid arthritis were negative, leading to a diagnosis of sero-negative rheumatoid arthritis, for which treatment with methotrexate was initiated. Read More

Non-infectious soft tissue lesions of the foot and ankle are relatively rare clinically. These include benign and malignant neoplasms, as well as non-neoplastic or pseudotumoral lesions such as ganglionic, synovial and epidermoid cysts, intermetatarsal and adventitious bursitis, inflammatory lesions like gouty tophi and rheumatoid nodules, Morton's neuroma, and granuloma annulare. A 48-year-old male with a history of medically treated tophaceous gout presented with left foot neuropathic pain and paresthesia, in the setting of a well-circumscribed soft tissue lesion of the second intermetatarsal space, suspected to be a Morton's neuroma.

Granuloma annulare (GA) is a common benign inflammatory skin condition classically presenting as skin-colored to erythematous dermal papules and annular plaques. Histologically, GA displays a dermal granulomatous infiltrate with palisaded histiocytes surrounding focally altered collagen. The exactly etiology of GA remains unknown, but it has been associated with trauma, various infections, diabetes mellitus, malignancy, thyroid disease, dyslipidemia, and several medications.
