Primary gastric lymphoma is the most frequent extra nodal primary site for non-Hodgkin's lymphoma (NHL) and is itself uncommon. Moreover, a massive infiltration of all stomach (from cardias to antrum) simulating a linitis plastica, it's rare. We present a case report of this atypical presentation of primary gastric NHL in a 73 year old females. The patient came to our observation complaining of dyspepsia, epigastric pain and vomiting from 7 months associated with weight loss and asthenia. Physical examination revealed an epigastric palpable mass. Computed tomographic findings has been necessary to confirm that the massive infiltration of gastric wall (from cardias to pylorus) was ascribed to lymphoma. Dawson's criteria was respected to define primary gastric NHL and was performed a total gastrectomy with systematic lymphadenectomy. The histopathological evidences have confirmed clinical diagnosis of primary gastric NHL. Preoperative diagnosis to clarify the nature of lesions (primary or not) and accurate staging of neoplasm before the operation are indispensable for a correct therapeutic approach; in according to the Ann Arbor classification modified by Musshoff our cases was stage IIE and radical gastrectomy with systematic lymphadenectomy was performed. Surgical resection is generally considered to have a definitive role in the treatment of primary gastric lymphoma specially for the stage IE and IIE.

Gastric metastases from lung adenocarcinoma are rare. Because gastric metastasis grossly resembles advanced gastric cancer, it is difficult to diagnose gastric metastasis especially when the histology of the primary lung cancer is adenocarcinoma. We describe a case of gastric metastasis from primary lung adenocarcinoma mimicking Borrmann type IV primary gastric cancer. A 68-year-old man with known lung adenocarcinoma with multiple bone metastases had been experiencing progressive epigastric pain and dyspepsia over one year. Esophagogastroduodenoscopy revealed linitis plastica-like lesions in the fundus of the stomach. Pathologic examination revealed a moderately differentiated adenocarcinoma with submucosal infiltration. Positive immunohistochemical staining for thyroid transcription factor-1 (TTF-1) and napsin A (Nap-A) confirmed that the metastasis was pulmonary in origin. The patient had been treated with palliative chemotherapy for the lung cancer and had lived for over fifteen months after the diagnosis of gastric metastasis. Clinicians should be aware of the possibility of gastric metastasis in patients with primary lung adenocarcinoma, and additional immunohistochemical staining for Nap-A as well as TTF-1 may help in differentiating its origin.

Breast cancer metastases to the gastrointestinal tract are rare, with a median time interval from the diagnosis of the primary tumor to metastasis up to 7 years. The stomach is the most frequent metastatic site and invasive lobular carcinoma is the type with the highest affinity to the digestive system. We report the case of an 84-year-old female patient, with a past medical history 20 years earlier of invasive lobular carcinoma of the breast, who presented for dyspepsia. Upper endoscopy revealed hypertrophic gastric folds compatible with primary linitis plastica. Histology showed proliferation of malignant poorly cohesive cells. Immunohistochemistry stain showed intense positivity of estrogen receptors and anti-GATA-binding protein 3 nuclear antibodies, and absence of the human epidermal growth factor receptor 2. These findings confirmed the diagnosis of a metachronous metastasis of the invasive lobular breast adenocarcinoma. Considering metastases from breast cancer is crucial when patients with any subtle gastric symptom and a past medical history of invasive lobular adenocarcinoma of the breast seek medical advice, even though more than 20 years after primary breast cancer. Immunohistochemistry is the key to final diagnosis as these lesions can endoscopically and histologically mimic primary linitis plastica.
