Idiopathic granulomatous lobular mastitis (IGLM) is an uncommon and rare chronic inflammatory breast disease. The exact etiology is not known. Although various etiologies have been implicated, autoimmunity is favored and widely accepted. In countries with a high prevalence of tuberculosis, the diagnosis of IGLM is often challenging. Clinical presentation is quite variable. Ultrasonography and mammography findings lack specificity. Fine-needle aspiration (FNA) cytology features of idiopathic granulomatous mastitis (IGM) have been described in few reports, but they are still debatable. We report the case of a 36-year-old female with a hard lump in the left breast. Aspiration cytology smears showed many well-formed epithelioid granulomas and few scattered epithelioid cells. The background showed numerous polymorphonuclear leukocytes with few reactive lymphoid cells and foreign-body giant cells. There was no necrosis. Acid-fast bacilli (AFB) and fungal stains did not show AFB and fungal hyphae. A diagnosis of IGM was suspected on aspiration cytology. Histopathology examination confirmed the diagnosis. To conclude, though tuberculosis is highly prevalent in India, if breast FNA smears show epithelioid granulomas with numerous polymorphonuclear leukocytes with no necrosis or AFB, IGLM must be suspected.

Lymphangiomas are a rare benign proliferation of the lymphatic system. Intra-abdominal lymphangioma is rare and accounts for <5% of lymphangioma cases. Cystic mesenteric lymphangioma is extremely rare and accounts for <1% of abdominal lymphangiomas. Abdominal swelling, pain, vomiting, and constipation are common clinical presentations. We report a case of a 5-year-old boy with no significant medical history of illness who presented with acute abdomen. Preoperative accurate diagnosis by radiological modalities is very difficult. Surgical excision is the choice of treatment. Definitive diagnosis requires histopathological examination.
