Cysticercosis, a major health issue in developing countries, is caused by the larval stage of Taenia solium. Disseminated cysticercosis (DCC), which is characterized by widespread cysticerci in various tissues, is rare and often asymptomatic. Here, we report the case of a 50-year-old man from rural Nepal with distal cholangiocarcinoma and DCC involving the skin, brain, orbit, tongue, soft palate, heart, and abdominal organs. Despite the presence of abdominal pain, obstructive jaundice, anemia, and significant weight loss-symptoms indicative of biliary malignancy-there were no symptoms typical of DCC. Diagnostic imaging confirmed DCC and stomach-preserving pancreaticoduodenectomy was performed. Histopathological examination of the periampullary mass revealed distal cholangiocarcinoma. Postsurgical treatment for DCC included steroids, carbamazepine, and antiparasitic therapy with albendazole. The coexistence of cysticercosis and neoplasia, though uncommon, necessitates thorough diagnostic evaluation. This case underscores the clinical complexity and highlights the need for comprehensive management of concurrent conditions.

Blau syndrome (BS), is an autoinflammatory granulomatosis disease characterized by a distinct triad of skin, joint, and eye disorders similar to those of sarcoidosis, but the lung involvement frequently observed in sarcoidosis are rare. Granulomas from patients with BS displayed a distinct morphology indicating an exuberant chronic inflammatory response. Patients with BS may have granulomatous lung lesions, which require early diagnosis. To determine whether therapeutic intervention is needed for lung lesions, examining transbronchial lung cryobiopsy specimens and accumulating cases of BS with lung involvement could be contributed to improving BS management in the future.

BACKGROUND: Mesotherapy is a popular cosmetic procedure for localized delivery of substances. However, due to the lack of standardized processes, there are potential risks of adverse reactions. Granulomas formation is one of the chronic reactions which impose significant physical and mental burdens on patients.
OBJECTIVE: The aim of this analysis is to evaluate the safety and feasibility of combining intense pulsed light (IPL) with intralesional corticosteroids for treating noninfectious granulomas after mesotherapy.
METHODS: This retrospective observational case series included patients who suffer from noninfectious granulomas after mesotherapy and received combination of IPL and intralesional corticosteroids treatment between October 2021 and December 2022 at Peking University Shenzhen Hospital, Shenzhen, China. The process and effect were analyzed and summarized.
RESULTS: Among the seven patients, five expressed extreme satisfaction with the efficacy, while two was slightly satisfied. The physicians believed that all patients had shown significant improvement. No adverse reactions or recurrences were observed during follow-up.
CONCLUSIONS: Based on this analysis, the application of the combined treatment in patients suffering from noninfectious granuloma due to mesotherapy demonstrates good clinical efficacy and safety, making it worth considering as a treatment option.

Contracturing granulomatous myositis is a rare myopathy in which patients present with flexion contractures of the upper limbs in addition to slowly progressive muscle weakness and pain. Whether it represents a distinct nosological entity remains a point of discussion. We present a patient with isolated granulomatous disease of the muscle that responded very well to intravenous immunoglobulins after treatment failure of corticosteroids and methotrexate.

BACKGROUND: VEXAS is a recently described inflammatory disease caused by mutations in the UBA1 gene. Symptoms are diverse and include fevers, cartilaginous inflammation, lung inflammation, vasculitis, neutrophilic dermatoses, and macrocytic anemia. Cytoplasmic inclusions in myeloid and erythroid progenitors in the bone marrow are a hallmark feature. Here we report the first case of VEXAS with non-caseating granulomas in the bone marrow.
METHODS: A 62-year-old Asian male presented with fevers, erythema nodosum, inflammatory arthritis, and periorbital inflammation. Labs were significant for persistently elevated inflammatory markers and macrocytic anemia. Over the years his symptoms and inflammatory markers only improved with glucocorticoids and recurred when prednisone dose was lowered below 15-20 mg daily. He underwent bone marrow biopsy showing non-caseating granulomas and PET scan showing hilar/mediastinal lymphadenopathy. He was initially diagnosed with IgG4-related disease (treated with rituximab) and later sarcoidosis (treated with infliximab). After failing these agents, the possibility of VEXAS was considered and later confirmed by molecular testing.
CONCLUSIONS: To the best of our knowledge, this is the first observation of non-caseating granulomas in VEXAS, a cautionary reminder of its non-specificity since misinterpretation can lead to diagnostic delay. VEXAS should be in the differential in patients with symptoms of chronic inflammation responding positively to steroids (but not to B-cell depletion or TNF inhibition), which is in line with previous literature.

This ChatGPT-driven case report describes a unique presentation of neurosarcoidosis. The patient, a 58-year-old female, initially presented with hoarseness and was found to have bilateral jugular foramen tumors and thoracic lymphadenopathy. Imaging revealed significant enlargement and thickening of the vagus nerve and a separate mass of the cervical sympathetic trunk. The patient was referred for an ultrasound-guided biopsy of the abnormal neck masses to establish a pathologic diagnosis. The patient subsequently underwent neck dissection for exposure of the vagus nerve and isolation of the great vessels in preparation for a transmastoid approach to the skull base. The presence of multifocal tumors prompted the need for a biopsy, which ultimately revealed sarcoid granulomas in the nervous system. The patient was diagnosed with neurosarcoidosis. This case highlights the potential for sarcoidosis to affect the nervous system, with multiple cranial nerve involvement, seizures, and cognitive impairment. It also emphasizes the need for a combination of clinical, radiological, and pathological findings for an accurate diagnosis of neurosarcoidosis. Additionally, this case highlights the utility of natural language processing (NLP), as the entire case report was written using ChatGPT. This report serves as a comparison of the quality of case reports generated by humans versus NLP algorithms. The original case report can be found in the references.

Cutaneous sarcoidosis can manifest after doing a permanent makeup (PMU), such as tattooed eyebrows. A 41-year-old Chinese woman, with a tattoo in the eyebrows, developed yellow-brown plaques in her eyebrows for several months. A dermatopathological examination revealed non-caseating granulomas consistent with cutaneous sarcoidosis. For months, topical corticosteroids were applied, which showed little effect. Furthermore, a physical evaluation of the patient revealed no apparent involvement of other body organs except bilateral hilar lymphadenopathy with few diffuse reticulonodular opacities. On the basis of fully informed consent, the patient agreed to a 6-month initial follow-up to avoid unnecessary PMU.

Sarcoidosis is a systemic inflammatory disease of unknown aetiology. Given its complex clinical presentation, the disorder frequently causes diagnostic challenges. In most cases, the primary manifestation is in the lungs and mediastinum. Breast involvement as the primary manifestation of sarcoidosis is rare, accounting for less than 1% of cases. The authors present the case of a 44-year-old woman whose disease first manifested as multiple non-specific BIRADS 4 lesions in both breasts, accompanied by axillary lymphadenopathy, detected by ultrasound examination. The lesions were not visible on mammography. The course of the disease was clinically silent, with intermittent remissions, until the complete resolution of focal breast lesions on ultrasound after two years of follow-up. The paper presents an algorithm for the management of multifocal breast pathology with associated lymphadenopathy, which led to the prompt verification of sarcoidosis.

UNASSIGNED: Microneedling is a common non-invasive procedure used for a variety of dermatologic conditions. It is associated with a low rate of adverse events which are typically temporary. Hypersensitivity reactions, including granuloma formation, are a rare adverse event, with only 10 cases previously reported.
UNASSIGNED: We report a case of a 49-year-old female who presented with asymptomatic edematous erythematous annular plaques on her left cheek following a microneedling procedure in which a Vitamin C cosmeceutical was applied to the skin beforehand. Skin biopsy confirmed non-necrotizing granulomatous dermatitis with negative tissue cultures. Systemic workup for sarcoidosis was negative.
UNASSIGNED: Delayed facial granulomatous reaction is an uncommon adverse event following microneedling. Increased risk may be related to peri-procedure use of cosmeceuticals such as Vitamin C. Given the popularity of microneedling, and that it is an unregulated procedure, it is important for dermatologists to be aware of this possible sequela in order to counsel patients appropriately and understand management options.

Sarcoidosis is a multisystem, inflammatory granulomatous disease that rarely involves breast tissue. The pathophysiology of this chronic granulomatous condition is not well understood but is thought to be multifactorial, involving environmental influences causing an amplified immune response. A key histomorphology feature in sarcoidosis is the presence of non-necrotizing granulomas. In this case, we report a 41-year-old African-American man with a known history of sarcoidosis of the lung who presented with gynecomastia and bilateral breast tenderness with palpable nodules. Subsequent biopsy and microscopic examination of the breast nodules revealed diffuse involvement with non-necrotizing granulomas in both breasts. A final diagnosis of extensive sarcoidosis involving breast tissue was rendered after excluding other causes of non-necrotizing granulomas. The patient underwent a bilateral mastectomy to remove the breast nodules. This case discusses sarcoidosis involving an unusual site.
