Abstract
Isolated splenic metastasis from lung cancer is a very rare occurrence with only a few reports available. Here, we report the case of a 82-year-old male who underwent a bilobectomy for a lung squamous cell carcinoma and 16 months later developed an isolated splenic metastasis. Additionally, previous reports are reviewed and discussed.
Highlights
Isolated splenic metastasis from lung cancer is an exceedingly rare event
We present the case of an 82-year-old male with previously excised lung squamous cell carcinoma who developed local recurrence and a splenic metastasis
Pathologic findings consisted of a splenic metastasis with the red pulp being invaded by a moderately differentiated squamous cell carcinoma with keratinization and intercellular bridges (Figure 3 and 4)
Summary
We present the case of an 82-year-old male with previously excised lung squamous cell carcinoma who developed local recurrence and a splenic metastasis. Follow-up was lost and a new CT scan was only performed one year later This exam revealed an interlobular thickening and an enlargement of the splenic lesion measuring 6.5 × 6.4 cm (Figure 2). Pathologic findings consisted of a splenic metastasis with the red pulp being invaded by a moderately differentiated squamous cell carcinoma with keratinization and intercellular bridges (Figure 3 and 4). The colonic lesion consisted of a moderately differentiated Adenocarcinoma composed of complex and irregular glands and tubules, with loss of nuclear polarity and necrotic debris It invaded the subserosal and 3 out of 19 lymph nodes were compromised (pT3pN1b) - Figure 5. Twelve months after the procedure, the patient remains well, with stable lung disease and no other sites of disseminated metastasis from both cancers
