Skin metastases as first manifestation of lung cancer

Non-Specific Onset of Pulmonary Adenocarcinoma

Skin metastases are rarely found in lung cancer compared to other types of neoplasia. Of the types of lung cancer that can have skin metastases, the most common one is adenocarcinoma. Pulmonary cancer metastasizing to the skin has poor prognosis, usually the survival rate of the patients is 4-6 months. We present the case of a 59-year-old woman, smoker, high blood pressure, dyslipidemia, with two skin ertitemato-nodular lesions, incompletely delimited, with a diameter of 4-5cm, in the left arm (1/3 medio-external) and left latero-thoracic (near IV intercostal space) area, discovered during a regular medical examination at her family doctor’s practice. After multiple clinical and paraclinical investigations, almost 3 months after the initial presentation, the patient was diagnosed with stage IV pulmonary adenocarcinoma with supra and subdiaphragmatic lymph-node metastases, soft tissue metastases, liver metastases and breast metastases. Oncological treatment was initiated, but the patient's progression was unfavorable, her passing occurring 6 months after being diagnosed.

Primary small cell carcinoma of the lung presenting with breast and skin metastases

Cutaneous metastases originating from an internal cancer are relatively uncommon in clinical practice, and metastatic lesions to the breast are rarer than those to the skin. Skin metastases of lung cancer, which may be the first sign of the disease, usually indicate progressive disease and a poor prognosis. We describe a 47-year-old male who presented with recurring masses in the lumbar region bilaterally and the right breast. Immunohistochemical findings and radiological imaging suggested lung cancer. This is the first reported case of small cell lung cancer metastasizing to two separate, uncommon sites, the skin and breast.

[The metastases to the head and neck region from distant primary localization]

INTRODUCTION

Distant metastases to the head and neck region, with primary tumor located outside the head and neck, presents often a diagnostic problems, especially when metastases are an exclusive signs and symptoms of the disease. In most of this cases there is no chance for curative therapy, and optimum palliation is the goal of the treatment.

AIM

The description and analysis of clinical and prognostic factors, which could establish the optimum diagnostic formula, and predict the prognosis in distant metastases to the head and neck region.

MATERIAL AND METHODS

The study of 44 cases diagnoses and treated in 2001-2006 in Dept. ORL H&N Surgery. The analysis was based on current observations and case records documentation.

RESULTS/CONCLUSIONS

In the most of cases (39/44) the distant metastases to the head and neck regions presented a part of generalized malignant neoplastic disease, but in 14/44 cases that was a first warning symptom. All of this 14/44 cases presented as a metastases to the IV and V lymph nodes region. The most common primary sides were found in the lung. The average survival within the analyzed group was only 7,2 months.
