Cutaneous metastasis from internal malignancies is rare and represents about 2% of all skin tumors. Cutaneous metastasis occur in about 0.2%–0.4% of gastric carcinoma cases, most commonly affecting the abdomen with neck, head, eyebrow, axilla, chest, and fingertips being the other sites. Here, we present a case in which cutaneous metastases presenting as multiple crateriform nodules were the first presenting signs of gastric adenocarcinoma.

| Introduction|| |
Cutaneous metastasis from internal malignancies represents about 2% of all skin tumors and occurs in about 0.6%–10.4% of patients. The metastases may be the presenting symptom of a malignancy or may herald recurrence of a treated malignancy. Here, we report a case presenting with multiple ulcerated nodules with crateriform appearance in the head and neck, which was subsequently found out to be cutaneous metastases of gastric adenocarcinoma.
| Case Report|| |
A 65-year-old, nonsmoker male presented to the outpatient department of a tertiary hospital with complaints of initially asymptomatic, multiple skin-colored solid raised nodules for 3 months over head and neck [Figure 1]. Few of the larger nodules developed ulceration [Figure 2]. History of malaise and weight loss in the past 5 months was present. There was no history of dysphagia, hematemesis, or melena or any other systemic complaints. On examination, a total of eight nodules were present in the forehead, scalp, and neck of size ranging from 0.5 cm × 0.5 cm to 3 cm × 2 cm. Ulceration was present in six of the nodules. The nodules were well-defined, nontender, hard on palpation and fixed to the underlying structures. Bilateral cervical and left supraclavicular lymph nodes were palpable which were firm to hard. There was no organomegaly. Pallor was found to be present, and on investigation, the patient had hemoglobin of 7 g/dl. Enzyme-linked immunosorbent assay was nonreactive for HIV1 and 2. Stool for occult blood was positive. All other biochemical and hematological investigations were within normal limit. Chest X-ray and ultrasonography of the abdomen were not contributory. Differential diagnosis of basal cell carcinoma, histoplasmosis, molluscum contagiosum, and keratoacanthoma was kept. Histopathological examination revealed diffuse dense infiltrate of large neoplastic cells within the reticular dermis, showing moderate variation in their nuclear size, color, and shape. The cells had moderate amount of bluish staining cytoplasm. The neoplastic cells showed acinar arrangement at some places and were arranged in solid islands of varying sizes at other places. Several dilated lymphatics were seen in the upper and mid dermis with the overlying epidermis unaffected. The impression was of metastasis of adenocarcinoma [Figure 3]. Further investigations for finding the primary including computed tomography scan of the abdomen and pelvis showed circumferential heterogeneously enhancing mural thickening at the antropyloric region of the stomach causing luminal narrowing. Endoscopic biopsy and histopathological examination of the stomach growth came out to be gastric adenocarcinoma [Figure 4], consistent with the cutaneous lesions proving them to be secondaries. The patient was referred to the oncology department following which he was lost to follow-up.

| Discussion|| |
Cutaneous metastasis from internal malignancies is rare, represents about 2% of all skin tumors, and occurs in about 0.6%–10.4% of patients. The most common sources of cutaneous metastasis in women are from the breast, colorectum, melanoma, and ovary, while in men, lung cancer, melanoma, colorectal and squamous cell carcinoma of the oral cavity, and renal cell carcinoma are the most common sources. 0.2%–0.4% of gastric carcinoma cases metastasize to the skin, most commonly affecting the abdomen with neck, head, eyebrow, axilla, chest, and fingertips being the other sites. Clinically, they present as solitary or multiple nodules and rarely as carcinoma erysipeloides, carcinoma en cuirasse, zosteriform metastasis, and neoplastic alopecia. Cutaneous metastasis usually occurs late after an internal malignancy; however, rarely, they may be the initial presenting symptom in about 0.5%–1% of cases. This sort or rarity can lead to a misdiagnosis of skin lesions, especially when they the diagnosis of an underlying malignancy is not made. The metastasis may occur through lymphatic spread hematogenous spread, direct contiguity, or iatrogenic implantation. Because they usually represent widespread terminal disease, prognosis is generally poor and the treatment is mainly palliative. For widespread cutaneous metastases, palliative therapy including radiotherapy, systemic chemotherapy, polychemotherapy, isolated limb perfusion, interferon alpha injections, cryotherapy, laser ablation, or radiofrequency ablation may be helpful. Owing to the poor prognosis, early diagnosis of cutaneous metastases has a profound effect on patient management and survival, and the dermatologist plays a key role in it, especially when the cutaneous metastases predated the diagnosis of internal malignancy.
| Conclusion|| |
The idea of reporting this case is to be on the lookout for internal malignancies whenever a patient, especially an elderly, presents with asymptomatic ulcerated nodules even in the absence of any systemic signs and symptoms.
