General Area

Collision tumor is a rare condition in which two neoplasms (usually benign and malignant), both growing in the same general area, collide with each other and become intermingled. We present histopathology and imaging correlation of xanthogranulomatous pyelonephritis coexistent with squamous cell carcinoma and osteogenic sarcoma of the kidney.

Abstract A 93-year-old woman developed a mass on her right lower eyelid that was present for more than 6 months but underwent rapid expansion during several weeks prior to her ophthalmological evaluation. Examination revealed an approximately 1.8 cm in diameter, fleshy, fungating growth involving more than 60% of the right lower eyelid. Excisional biopsy disclosed a neoplasm arising from the epidermis composed of adjoining basal cell and signet-ring squamous cell carcinoma, without a transition zone. The cells comprising the basal and squamous cell carcinomas were distinct immunophenotypically, with only the basal cell carcinoma reacting with Ber-EP4 and CAM 5.2 antibodies. To our knowledge, this case represents the first example of a collision tumor composed of basal cell and signet-ring squamous cell carcinoma.

Purpose A collision tumor consists of 2 different histologically distinct and topographically independent tumors merging in the same mass. In the head and neck region they are rare, with only 4 cases reported in the larynx. Case report A 60-year-old heavy smoker complained of a left submandibular lesion in October 2014. The lesion was excised and showed a poorly differentiated carcinoma, suggestive for adenocarcinoma. After a positron emission tomography-computed tomography scan showed increased metabolic activity in the left laterocervical region and right vocal cord, the patient underwent endoscopic biopsy of the lesion of the left piriform sinus, which was positive for moderately differentiated squamous cell carcinoma (SCC). He was then submitted to circular pharyngolaryngectomy, reconstruction with a radial forearm free flap, and bilateral neck dissection. The histopathologic examination showed an in situ and microinvasive SCC of the left pyriform sinus colliding with a high-grade, non-small-cell neuroendocrine carcinoma of the larynx. Conclusions To our knowledge, this is the first case described of laryngeal collision tumor comprising a neuroendocrine component. The choice of treatment of this kind of lesion is difficult because of the presence of 2 different histologies and of the controversial prognostic correlation of non-small-cell neuroendocrine neoplasms of the head and neck region.

Abstract Background The collision tumor consisted of two malignant tumors that independently developed and were contiguous or had invaded each other. Among the reports of malignant collision tumors, collision tumors consisting of lung cancer and malignant lymphoma are extremely rare. We report case of a lung collision tumor consisting of squamous cell carcinoma of the lung and diffuse large B-cell lymphoma.Case presentationA 74-year-old man was admitted to the hospital due to identification of an abnormal nodular shadow in the right upper lobe on chest computed tomography following a chest X-ray. At the time of admission, a swollen lymph node of 7 cm × 5 cm was palpated in the left neck, and serum examination showed an abnormally high level of soluble interleukin-2 receptor. Close examination led to a diagnosis of stage IA squamous cell carcinoma of the lung and stage IVA malignant lymphoma, and treatment for the malignant lymphoma was prioritized. However, due to progression of lung cancer, a right upper lobectomy with lymph node dissection was performed. Pathological findings showed that squamous cell carcinoma and malignant lymphoma were both present in the same lesion.ConclusionOnly two cases of collision tumors consisting of malignant lymphoma and primary lung cancer were reported [1] [2] and this case is considered to be the third rare case in the world. As the rate of complications with other malignancies in patients with diffuse large B-cell lymphoma is high, in the case of advanced stage malignant lymphoma, physicians must consider which treatment should be prioritized according to the degree of progression of coexisting solid tumors.
