Sarcoidosis Manifesting as Massive Splenomegaly: A Rare Occurrence

Multisystemic Sarcoidosis Presenting With Leg Ulcers, Pancytopenia, and Polyserositis Was Successfully Treated With Glucocorticoids: A Case Report and Literature Review

INTRODUCTION

Sarcoidosis is a chronic granulomatous disease of unknown etiology. A variety of studies have pointed out that almost every part of the body can be affected, but it most often affected the lungs and intrathoracic lymph nodes. However, cases of sarcoidosis involving multiple organs in one patient are rarely reported. We describe a unique case of sarcoidosis, which was characterized by multiorgan involvement, including leg ulcers, splenomegaly, pancytopenia, and polyserositis. Glucocorticoids were effective during the treatment of the above lesions. This case highlights the diversity of clinical manifestations of sarcoidosis and emphasizes the importance of its differential diagnosis and the periodical follow-up. These are crucial to physicians in the diagnosis and treatment of sarcoidosis.

MAIN SYMPTOMS AND IMPORTANT CLINICAL FINDINGS

A 30-year-old male complained about intermittent fever 3 years ago. A computed tomographic scan of the chest showed lymphadenopathy in the mediastinum and hilar regions. Routine blood tests showed leukopenia and mild anemia. The pathologic result of mediastinal lymph node biopsy was granulomatous lesions; thus, the patient was diagnosed with type II sarcoidosis without glucocorticoid therapy. In the following 2 years, the patient suffered from intermittent fever accompanied by dyspnea, fatigue, occasional cough, less sputum, and apparent weight loss. Abnormal physical examinations included leg ulcers and splenomegaly. Laboratory and physical tests revealed pancytopenia, polyserositis, and enlargement of lymph nodes. The pathological findings of leg ulceration, pleura, and left supraclavicular lymph node all suggested granulomas.

DIAGNOSIS INTERVENTIONS AND OUTCOMES

It strongly suggested sarcoidosis since tuberculosis, lymphoma, and connective tissue disease were all excluded. Due to severe conditions and multiorgan involvement, we tried to provide methylprednisolone for this patient. After 9 months of oral glucocorticoids therapy, his subjective symptoms as well as hematological and radiological findings were all improved. His leg skin ulceration and scab were also completely disappeared.

CONCLUSION

Sarcoidosis has diverse clinical presentations, and many patients present with atypical symptoms. It needs to be timely identified by the clinician and carefully differentiated from other diseases with similar findings so as to make an accurate diagnosis. In this case, the patient had a poor clinical response to glucocorticoids in the early stage of treatment due to the severe condition and multi-organ involvement. It is worth noting that the patient had improved significantly after 9 months of treatment of corticosteroids, which suggested that follow-up is critical.

Unusual Presentation Of Sarcoidosis: Case Report

Sarcoidosis is a multisystem granulomatous disease with polymorphic manifestations, of unknown etiology, that can affect any organ in the body, but most commonly the lungs [1,2,3]. Extrapulmonary involvement is common, can occur in association with or in the absence of intrathoracic disease, and all organs can be involved, but it is rare to find an isolated extrapulmonary disease (less than 10% of patients) [3,4]. On occasion, the presentation of sarcoidosis may be atypical.

We report a case of systemic sarcoidosis, with particular clinical data: extrathoracic onset with subdiaphragmatic lymph nodes, hepatomegaly and splenomegaly.

Late development of splenic sarcoidosis-like lesions in a patient with metastatic melanoma and long-lasting clinical response to ipilimumab

A male patient with Stage IV melanoma was treated with ipilimumab resulting in a long-lasting partial response according to RECIST criteria. However, twenty months after ipilimumab treatment, routine follow-up CT scan revealed new splenic lesions initially interpreted as indicative of progressive disease. Nevertheless, a biopsy was performed and histologic evaluation showed that the lesions did not contain malignant cells but rather constituted non-caseating epithelioid cell granulomas consistent with sarcoidosis. As the patient was asymptomatic no treatment was initiated and over the following months the splenic lesions slowly disappeared and to date the patient remains in remission. Ipilimumab is now widely used in the treatment of melanoma patients. Our case-report illustrates that physicians should consider the possibility of ipilimumab induced visceral sarcoidosis-like reactions, mimicking metastatic lesions, developing even many months after ipilimumab treatment. Thus, biopsy of such suspicious lesions is advisable to avoid misinterpretation as disease progression and unnecessary resumption of cancer therapy.

Sarcoidosis presenting as massive splenic infarction

Sarcoidosis is a multisystem granulomatous disease of unknown aetiology. Granulomatous inflammation involving the spleen is common and associated with splenomegaly. However, massive splenomegaly is a rare occurrence. Infrequently massive splenomegaly can result in splenic infarction. Massive splenic infarction in sarcoidosis has, to our knowledge, not been previously reported. We present a case of a woman presenting with massive splenic infarction and sarcoidosis confirmed by granulomatous inflammation of the liver.

Sarcoidosis manifesting as cardiac sarcoidosis and massive splenomegaly

Sarcoidosis is a multisystemic granulomatous disease of unknown etiology. We report an unusual case of sarcoidosis in a woman presenting with cardiac sarcoidosis and massive splenomegaly with a familial history of cardiac sarcoidosis. Cardiac sarcoidosis was diagnosed based on electrocardiogram, echocardiogram, 18F-fluoro-2-deoxyglucose positron emission tomography (18F-FDG-PET) and skin histological findings. We performed splenectomy to rule out malignant lymphoma, and histological findings confirmed sarcoidosis. After splenectomy, we initiated prednisolone therapy. After 20 months of diagnosis, she was symptom free. Echocardiography and 18F-FDG-PET may be a key diagnostic tool and prednisolone therapy may be safe, effective, and feasible for cardiac sarcoidosis.

Sarcoidosis presenting with massive splenomegaly in a child with a history of iridocyclitis and sensorineural deafness

Childhood sarcoidosis is a rare multisystemic disorder that can have variable clinical presentations. A triad of skin, eye, and joint involvement is common in children younger than 5 years; however, pulmonary disease is more common in older children, similar to adults. The authors report the case of a 10-year-old girl who presented solely with massive splenomegaly. Her history was significant for iridocyclitis and unilateral sensorineural deafness at 6 and 7 years of age, respectively. A gallium scan showed diffuse splenic uptake, and the pathology of the spleen was consistent with a noncaseating granuloma, with no evidence of malignancy. A work-up for infectious etiology was unremarkable. This case demonstrates that the challenge in diagnosing sarcoidosis in young children stems from its ability to present in several unique clinical scenarios. It also reinforces the importance of tissue evaluation and the exclusion of other differential diagnoses, such as lymphoma, to confirm the diagnosis of sarcoidosis.

Intra-abdominal complications of sarcoidosis

Sarcoidosis is an inflammatory disease characterized by non-caseating granulomas in the absence of other autoimmune processes, infectious diseases, or foreign agents. The etiology of sarcoidosis is not completely understood. Several organ systems can be affected, of which the most frequently involved include the lungs and lymph nodes. Intra-abdominal sarcoidosis is less common, but can be found in the absence of pulmonary or lymphatic disease. Intra-abdominal sarcoidosis is most often asymptomatic. However, long-standing unrecognized disease can result in life-threatening complications. The identification, monitoring and prevention of these complications will be discussed, with emphasis on both clinical and histological presentations of intra-abdominal sarcoidosis.

[Inflammatory reactions of the spleen]

Inflammatory reactions of the spleen occur in the context of two pathophysiological settings. First, lymphoid hyperplasia of the spleen can be the result of a principally physiological production of immune effector cells e.g. due to systemic viral infections, autoimmune diseases and acquired or inherited immunodeficiencies. Second, the spleen itself may be the target of a pathological inflammatory reaction; this setting is exemplified by abscess formation due to septicopyemic spread of bacteria and by granulomatous inflammations, e.g. due to tuberculosis or sarcoidosis. Differential diagnostic considerations have to include splenic inflammatory pseudotumors, mycobacterial spindle cell tumors and lymphomas with granulomatous or histiocyte-rich reactive changes.

'Surgical cure' for non-parathyroid hypercalcemia

BACKGROUND

Sarcoidosis is a granulomatous disease of unknown aetiology. Over 90% patients of sarcoidosis present with pulmonary findings. Other organs such as lymph nodes, skin, and joints may be involved. Isolated granulomatous disease confined to the spleen is rare.

CASE PRESENTATION

This report documents a rare case of isolated granulomatous disease of spleen presenting as hypercalcemia. After all possible causes for hypercalcemia were ruled out, splenectomy was done which proved diagnostic and therapeutic, as calcium levels returned to normal.

CONCLUSION

We propose that sarcoidosis should be kept in mind as a cause of unexplained hypercalcemia. Increased awareness of radiological features of splenic involvement in sarcoidosis, would help in diagnosis. We believe that we are reporting 9th case in the literature while writing this report.
