Abstract
BRAF-inhibitors have emerged as a promising targeted therapy for malignancies with BRAF mutations, particularly metastatic melanoma. However, granulomatous reactions including sarcoidosis and sarcoid-like-reactions have been reported as a consequence of BRAF-inhibition. It is important to adequately characterise these granulomatous reactions including cutaneous manifestations and systemic involvement, in order to guide investigations and management. A literature review was conducted to characterise the spectrum of granulomatous reactions associated with BRAF-inhibitors - identifying 55 reactions affecting 51 patients, with 37 reactions limited to cutaneous involvement. Further, possible correlation with cancer response, mechanisms of granuloma formation, as well as a proposed workup and management approach for these granulomatous reactions are presented.

Abstract
Sarcoidosis and sarcoid-like reactions (SLR) have been repeatedly reported in patients with melanoma treated with BRAF and MEK inhibitors. In the current study we present three patients that developed SLR under treatment with BRAF and mitogen-activated protein kinase (MEK) inhibitors for melanoma. Two patients developed mediastinal lymphadenitis with histological features of an SLR while on targeted therapy in the adjuvant setting, whereas one patient with metastatic melanoma developed granulomatous nephritis while receiving combination treatment with BRAF/MEK inhibitors and atezolizumab. In addition, we review the published literature on the pathogenesis, clinical characteristics, histologic features, imaging findings, and other potential useful diagnostic tools. We also address the need for a common terminology for these cases and propose an algorithm for the accurate diagnosis of BRAF/MEK inhibitor-induced SLR. We also review the currently available data on the treatment of these patients and suggest a treatment approach for SLR in patients with melanoma, as well as for the management of melanoma when SLR emerges.

Abstract
Sarcoidosis and sarcoid-like reactions have been associated with many solid tumors including malignant melanoma. There are reports of melanoma patients who develop sarcoidosis without having received any antineoplastic treatment, but there are also melanoma patients who have received immunotherapy or targeted therapy and, therefore, develop drug-associated sarcoidosis. Herein, we describe 2 cases of thoracic sarcoidosis which occurred in asymptomatic patients with known malignant melanoma. The first patient had metastatic disease, and she was under melanoma treatment with BRAF/MEK inhibitors at the time of sarcoidosis diagnosis. The second case involves a patient with early stage melanoma who had received no antineoplastic treatment. In both cases, the thoracic lesions were suspicious for metastatic involvement, and it was the biopsy which gave the diagnosis of granulomatous disease. Sarcoidosis induced by immune checkpoint or BRAF/MEK inhibitors seems to be more frequent in real-world studies than in large phase 3 melanoma trials. Sarcoidosis can mimic metastasis, predominately in mediastinum, representing a diagnostic pitfall. Therefore, biopsies must always be performed to exclude the metastatic spread before initiation of any antineoplastic treatment.

Abstract
Sarcoidosis is a multisystem inflammatory disease characterized by noncaseating granulomatous inflammation. While pulmonary sarcoidosis is most common, extrapulmonary involvement occurs in 50 to 74% of patients and can be the presenting abnormality in some patients. The diagnosis of sarcoidosis is based on a compatible clinical presentation in combination with granulomas on histology and exclusion of other causes. However, the absence of a diagnostic biomarker for sarcoidosis, in addition to the overlap of granulomatous inflammation and nonspecific clinical findings with other diseases, often results in a delayed diagnosis. Sarcoidosis overlap syndromes are typically described when sarcoidosis is diagnosed in the presence of another disease (concurrently or sequentially) with shared clinical and histologic features, or when sarcoidosis presents with clinical features typically observed in, but not diagnostic of, other diseases. Awareness of overlap syndromes is important for clinicians to avoid diagnostic errors and evaluate for concomitant diagnoses that may impact the management and outcome of sarcoidosis. This article is intended to provide an overview of these presentations and the most commonly associated diseases, with attention to their prevalence, clinical features, and reciprocal impacts on disease outcomes.

Abstract
Sarcoidosis is a chronic, multisystem, inflammatory disorder of unknown etiology that is characterized by noncaseating granulomas that impair normal organ functioning. Sarcoidosis predominantly affects the lungs, but the skin is often cited as the second most frequently involved organ. Cutaneous manifestations of sarcoidosis are highly variable and ongoing research seeks to better understand the relationship between clinical morphology and disease prognosis. Skin findings in patients with sarcoidosis can be "specific," in which sarcoidal granulomas infiltrate the skin, or they can represent a "nonspecific" reactive inflammatory process, as is seen in calcinosis cutis and erythema nodosum. Cutaneous sarcoidosis can be the initial presenting sign or develop later in the course of the disease. In some patients, the skin will be the most involved and impactful organ system and will drive therapy. In other cases, the skin will be an incidental or minor finding, but may be easily accessible for biopsy to confirm the diagnosis. There are many potential therapies for sarcoidosis, though no one therapy is universally effective.

Abstract
Combined BRAF and MEK inhibition is one of the first-line treatment strategies for patients with advanced BRAF-mutant melanoma. Sarcoid-like reactions (SLRs) have occasionally been described with melanoma systemic treatments such as immunotherapy or the BRAF inhibitor vemurafenib, but very few cases have been reported with dabrafenib and trametinib. Our aim was to better characterize SLR induced by this combination. We conducted a monocentric retrospective observational study among patients treated with dabrafenib and trametinib for BRAF-mutant advanced melanoma from January 2015 to March 2019. Patients presenting with histologically proven SLR were included. We also searched Medline database for all reported cases of SLR induced by targeted therapy. Of 63 patients on dabrafenib/trametinib combination, seven were diagnosed with a SLR. They all had specific cutaneous involvement, and one also displayed mediastinal and salivary glands involvement. None required systemic corticosteroids or dabrafenib/trametinib discontinuation. Three of them (43%) reached melanoma complete remission and are still on targeted therapy; and four patients progressed and died. A literature review yielded 22 additional cases of SLR induced by targeted therapy: the main affected organ was the skin, 11 patients (50%) had systemic involvement, five patients (23%) required systemic corticosteroids to reach partial or complete remission of SLR, 12 (55%) reached partial or complete response of melanoma while six (27%) progressed. BRAF and MEK inhibitors are potential triggers of SLR, although pathological mechanisms remain unclear. The mainstay of treatment is systemic or topical corticotherapy; targeted therapy discontinuation is usually not necessary.

Abstract
The development of cancer immunotherapy and targeted therapy has reached an important inflection point in the history of melanoma. Immune checkpoint inhibitors and kinase inhibitors are today's standard of care treatments in advanced melanoma patients. Treatment-related toxicities can be very intriguing and quite challenging. Sarcoidosis is a multisystemic granulomatous disease characterized by an aberrant immune response to unknown antigens, whereas sarcoid-like reactions (SLRs) refer to localized clinical features. We carried out a single-center observational study in patients with stage IIB-IV melanoma treated with BRAF/MEK inhibitors and immune checkpoint inhibitors. A description of the sarcoidosis-related manifestations was provided from patients' records. We observated eight cases of SLRs in a cohort of 200 patients. The clinical courses were characterized by a variety of symptoms, accompanied by cutaneous signs and extracutaneous manifestations such as bilateral, hilar lymphadenopathy. We identified a histologically granulomatous inflammation involving the skin, the lungs, and the lymph nodes. Two patients presented with cutaneous lesions only, and three patients had lung involvement only. Three patients achieved complete and partial response of the melanoma disease, and three patients had stable disease. Disease progression was documented in two patients. The reported immune-related adverse events were mild to severe and in most of the cases were continued without any treatment cessation. SLRs appear during treatment with both kinase and immune checkpoint inhibitors. Awareness of these can avoid misdiagnosis of disease progression and unnecessary treatment changes.

Abstract
New drugs against advanced melanoma have emerged during last decade. Target therapy and immunotherapy have changed the management of patients with metastatic disease. Along with its generalized use, drug toxicities have appeared and the skin is the target organ of a significant part of them. This revision summarizes the most common side effects and consensus management to improve the compliance of therapies and patients' quality of life. Among the BRAF inhibitors, main cutaneous side effects are photosensitivity, plantar hyperkeratosis, and the appearance of verrucal keratosis or squamous cell carcinoma. Special attention must be paid to the development of new primary melanomas or changes on nevi during BRAF inhibitor therapy. The most common cutaneous side effects of immunotherapy are rash, pruritus, and vitiligo. It remains controversial the possible role of these toxicities as markers of response to therapy.

Abstract
BRAF inhibitors (vemurafenib and dabrafenib) are commonly prescribed in BRAF-mutant metastatic melanoma and allow improvement of the overall survival and progression-free survival. They are, however, accompanied by many adverse effects which mainly affect the skin. We observed on computed tomographic scans in three different patients after 3 months of treatment, the onset of osteosclerotic lesions. In parallel, the computed tomographic scans showed a significant reduction in all of the previously identified metastases in all patients. The occurrence of such bone modifications under treatment was reported previously in others cancers, such as inoperable non-small-cell lung cancers under epidermal growth factor receptor inhibitors, as the 'osteoblastic bone flare phenomenon'. However, it had never been reported in melanoma patients treated with targeted therapies, and the results of two performed bone biopsies are reported here. This phenomenon is generally believed to indicate a better response under treatment, whereas in our study, the patients experienced, after a short partial response, a severe cerebral relapse leading to death. Finally, although its physiopathological mechanisms are poorly understood, the occurrence of tumor-free osteosclerotic lesions in patients under BRAF inhibitors should not be misinterpreted as a progression of the disease.

Abstract
With the introduction of hybrid imaging technologies such as PET/CT and recently PET/MRI, staging and therapy-response monitoring have evolved. PET/CT has been shown to be of value for routine staging of FDG-avid lymphomas before as well as at the end of treatment. For interim staging, trials are ongoing to evaluate the use of PET/CT. In melanoma, PET/CT can be recommended for stages III and IV diseases for initial staging and before surgery. Studies investigating the use of PET/CT for early therapy response are promising. The role of PET/MR in lymphoma and melanoma imaging has to be defined because no larger studies exist so far. There may be an application of PET/MR in research especially for tumor characterization and therapy response. Furthermore, the potential role of non-FDG tracers is elucidated regarding the assessment of treatment response in targeted drug regimens.

Abstract
BACKGROUND Vemurafenib significantly improved overall survival compared with dacarbazine in patients with metastatic or unresectable BRAF V600E-positive melanoma in the BRIM-3 trial. However, vemurafenib was associated with a number of skin-related adverse events (AEs). OBJECTIVES To investigate the incidence and management of vemurafenib-associated skin AEs. METHODS This retrospective, observational study included adult patients with stage IIIC or IV melanoma who received vemurafenib between March 2010 and August 2013. Patients received oral vemurafenib 960 mg twice daily, with dose interruptions and reductions allowed for AE management. RESULTS In total 107 patients were treated with vemurafenib during the study period. The most frequent clinically important skin-related AEs were rash (64%), squamoproliferative growths (41%), photosensitivity (40%) and squamous cell carcinoma (SCC) or keratoacanthoma (KA; 20%). Rare cases of granulomatous dermatitis and cutaneous T-cell lymphoma were also found. Rash was manageable with corticosteroids and dose modifications; squamoproliferative growths and SCCs/KAs were treated with cryotherapy and surgical excision, respectively. Patients were counselled regarding phototoxicity. The uncontrolled nature and retrospective design of the study, and the small patient numbers are limitations. CONCLUSIONS Vemurafenib appears to have a predictable and manageable AE profile. Proactive management can limit the impact of AEs on patients, allowing treatment to continue despite toxicities.

Abstract
Sarcoidosis is a systemic inflammatory disease characterized by the development of noncaseating granulomas in multiple organ systems. Many hematologic malignancies and solid tumors, including melanoma, have been associated with sarcoidosis. We describe the clinical and pathologic findings of a 54-year-old man with melanoma-associated sarcoidosis. In addition, we not only review the literature describing characteristics of other melanoma patients with sarcoidosis, but also the features of melanoma patients with antineoplastic therapy-associated sarcoidosis. Sarcoidosis has been described in 80 melanoma patients; sufficient information for analysis was provided in 39 of these individuals. In 43.6% of individuals (17 out of 39), sarcoidosis was directly associated with melanoma; in 56.4% of oncologic patients (22 out of 39), sarcoidosis was induced by antineoplastic therapy that had been administered for the treatment of their metastatic melanoma. The discovery of melanoma preceded the development of sarcoidosis in 12 of the 17 (70.5%) individuals who did not receive systemic treatment. Pulmonary and/or cutaneous manifestations of sarcoidosis were common among both groups of patients. Most patients did not require treatment for sarcoidosis. Melanoma patients—either following antineoplastic therapy or without systemic treatment—may be at an increased risk to develop sarcoidosis. In antineoplastic therapy naive melanoma patients, a common etiologic factor—such as exposure to ultraviolet light—may play a role in their developing melanoma and sarcoidosis.

BRAF inhibitors: experience in thyroid cancer and general review of toxicity. Discov Oncol 2014; 6:21-36. [PMID: 25467940 DOI: 10.1007/s12672-014-0207-9] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2014] [Accepted: 11/11/2014] [Indexed: 12/20/2022] Open
Abstract
The US Food and Drug Administration-approved BRAF inhibitors, vemurafenib and dabrafenib, have demonstrated superior efficacy in patients with BRAF-mutant melanomas but have limited efficacy in BRAF-mutant colorectal cancer. Little is known at this time regarding BRAF inhibitors in thyroid cancer. Initial reports in patients with progressive, radioactive iodine-refractory BRAF-mutant papillary thyroid cancer suggest response rates of approximately 30-40%. In this review, we discuss BRAF inhibitors in the context of thyroid cancer, the toxicities associated with BRAF inhibitors, and the suggested management of those toxicities. The management of vemurafenib and dabrafenib toxicities is applicable across all tumor types and may serve as a practical guide to their use.

Abstract
Sarcoidosis is a systemic granulomatous disease characterized by the presence of non-caseating granulomas. Its etiology remains obscure. A plausible hypothesis suggests that a complex interplay of host factors, infectious processes, and non-infectious environmental factors, matched with a susceptible genetic background, results in a pathway that leads to systemic granulomatous inflammation. Although presentations of sarcoidosis vary enormously, multi-organ involvement is a common feature. Cutaneous involvement occurs in about 25% of patients with protean manifestations and variable prognoses. Skin manifestations are divided into specific lesions with histopathologically evident non-caseating granulomas and nonspecific lesions arising from a reactive process that does not form granulomas. A peculiar form of cutaneous sarcoidosis is represented by sarcoidal lesions at sites of trauma that has caused scarring. The pathogenesis of scar sarcoidosis remains unknown. Scar sarcoidosis is also associated with herpes zoster infection, surgery, and tattooing. Such heterogeneous events, along with those at the sites of chronic lymphedema, thermal burns, radiation dermatitis, and vaccinations, occur on areas of vulnerable skin labeled "immunocompromised districts". Numerous options are available for the treatment of cutaneous sarcoidosis. Although corticosteroids remain the treatment of choice for initial systemic therapy, other nonsteroidal agents have proven effective and therefore useful for long-term management. Tumor necrosis factor-α antagonists such as infliximab may have a role in the treatment of cutaneous sarcoidosis, especially in refractory cases that are resistant to standard regimens. Elucidation of the relationship of sarcoidal granulomas with malignancy and immunity may facilitate a better understanding of some pathomechanisms operating in neoplastic and immunity-related disorders.

Abstract
L’année 2013 a été l’année des études génétiques de type GWAS (Genome wide association studies) au service de maladies fréquentes (psoriasis et dermatite atopique) visant à identifier des gènes candidats et celles des grandes cohortes de population tirées de registres publics ou privés. Ainsi des corrélations épidémiologiques sont déclinées : psoriasis et surrisque vasculaire, psoriasis et pathologies ORL, rosacée et migraines, acné et habitudes alimentaires, eczéma et carcinome basocellulaire, vitiligo et moindre risque de cancers cutanés, lupus cutané Ro/SS-A et cancer, eczéma chronique et inhibiteurs calciques, pemphigoïde et diurétiques de l’anse. Les liens entre isotrétinoïne et MICI ne sont pas confirmés. Ceux liant azathioprine et cancers cutanés le sont. Des toxidermies nouvelles voient le jour (pigmentations à l’interféron, hypodermites et sarcoïdose aux inhibiteurs de BRAF muté, toxidermies au vandétanib, etc.) et des toxidermies anciennes sont « revisitées » (patch-tests dans les toxidermies sévères, pigmentation à l’hydroxychloroquine, dermatoses neutrophiliques à l’azathioprine). Diane35® a fait une fausse sortie en janvier 2013 mais le tétrazépam, lui, a fait une vraie sortie en juillet 2013. Des aspects originaux de différentes infections cutanées sont abordés et des données nouvelles sur les MST (méningococcémies et homosexuels masculins, PVH, herpès, syphilis congénitale). Enfin, quelques articles concernant la dermatoscopie, la microscopie confocale et la dermatologie esthétique seront discutés.
