Adenocarcinoma Of The Lung

Lung cancer is the leading cause of cancer death in the United States, with more than 230,000 new cases, and approximately 150,000 deaths estimated for 2018. Lung cancer most commonly metastasizes to the brain, liver, lungs, bone, and adrenal system; however, there have been several cases of spread to soft tissues, with an incidence rate of approximately 0.75-9%. The objective of this case report is to highlight an unusual presentation of metastatic adenocarcinoma of the lung. In this case report, patient presented with a 3 × 3  cm soft tissue mass on the back. The mass was slowly growing but had become more painful and wished to have it excised. Preoperatively, the mass was suspected to be a sebaceous cyst but intraoperatively had deep attachments and other suspicious findings. Pathology had a positive immunoprofile for metastatic adenocarcinoma favoring a lung primary. Given this presentation of metastases, the prognosis is poor with a survival time decreasing to around 5 months. Overall, this case reinforces the importance of sending all soft tissue masses for final pathology with accurate labeling and the importance of immunohistochemical testing in aiding the identification of the primary.

Kimura disease is a rare benign chronic inflammatory disorder of unknown etiology that typically involves lymph nodes and soft tissues. This disease is most common in middle-aged Asian men. Although the disorder most frequently involves the head and neck region, it has also been reported to involve the extremities. Lesions typically show follicular lymphocytic hyperplasia with prominent interfollicular venules and a mixed inflammatory infiltrate, including numerous eosinophils. We describe a case of Kimura disease in a 29-year-old female presenting with a slowly enlarging, painless soft tissue mass in her left wrist for five months. The lesion was non-tender, mobile, and compressible. Lab results were significant for peripheral blood eosinophilia and elevated IgE. Microscopically, the mass was circumscribed, with apparent fibrous capsule or pseudocapsule, prominent high-endothelial venules, and inflammatory cells consisting of lymphocytes and eosinophils. There were prominent secondary B-lymphocytic follicles with germinal centers containing many penetrating small blood vessels, and some follicles exhibiting follicle lysis and a small amount of eosinophilic extracellular material. Polykaryocytes were noted in many germinal centers. Angiolymphoid hyperplasia with eosinophilia, a main differential diagnosis of Kimura disease, was considered; however, the combined clinical and morphologic findings appeared to be more consistent with Kimura disease, particularly in the context of eosinophilia and elevated IgE level. Kimura disease may present as a rare cause of a soft tissue mass and a diagnostic challenge for clinicians and pathologists, especially in less common sites such as the wrist.

Introduction. Soft tissue mass following total hip arthroplasty raises several differential diagnoses not limited to infection, hematoma, wear debris, malignancy, and bursitis. Rice body formation in the hip region is an uncommon process denoting a chronic inflammation. We report here the second case of its kind in the medical literature of a wide symptomatic rice-like body cyst complicating a total hip arthroplasty. Case Presentation. This is the case of an 82-year-old white female, presenting with a warm, red, and inflated groin five years after revision of right total hip arthroplasty. Surgical intervention reveals a large well circumscribed cyst containing well-organized rice-like bodies. This eventuality was never reported in differential diagnosis of hip periprosthetic soft tissue masses before. Conclusion. This case report helps widening the array of the differential diagnosis in patients presenting with a slow growing soft tissue mass following total hip arthroplasty, making rice-like bodies cyst a valid one to consider.

Exostosis, osteoma, and adenoma are the most commonly encountered benign lesions in the external auditory canal. Herein, we report a case of the mass arising from the external auditory canal in a 24-year-old Japanese man. CT revealed the soft tissue mass without bony erosion, and MRI revealed that the mass showed a homogenous, iso signal intensity on a both T1- and T2-weighted image, suggesting that the mass is a benign tumor such as adenoma. Pathological examination showed that the specimen demonstrated xanthogranuloma in the external auditory canal. Although xanthogranuloma of the external auditory canal is extremely rare, otolaryngologists should recognize this condition during the inspection of the external auditory canal.
