Abstract
BACKGROUND

The recognized pattern of cervical lymph node metastasis (CLNM) of papillary thyroid carcinoma involves a stepwise route. Contralateral lymph node skip metastasis is very rare. In addition, the patient in our case report also suffered from a breast carcinoma accompanied by left supraclavicular lymphadenopathy, which made it difficult to distinguish the origin of the CLNM. Based on this case, we recommended that more detailed physical and imaging examinations are needed for patients with uncommon cervical lymphatic metastasis of primary cancer.

CASE SUMMARY

A 53-year-old women was admitted to the hospital for a neck mass in the left cervical region that had existed for 2 mo. The neck mass was suspected to be an enlarged lateral LN originating from papillary thyroid microcarcinoma of the contralateral thyroid lobe, according to ultrasound and ultrasound-guided fine needle aspiration biopsy. The patient underwent total thyroidectomy and radical cervical LN dissection. Postoperative pathology confirmed the diagnosis of papillary thyroid microcarcinoma with contralateral lymphatic skip metastasis. Unfortunately, a breast cancer was discovered 4 mo later, which was accompanied by ipsilateral supraclavicular LN metastasis. She accepted neoadjuvant chemotherapy and subsequent left modified radical mastectomy for treatment. The patient is currently receiving postoperative radiotherapy, and no local recurrence was observed in the 6-mo follow-up after surgery.

CONCLUSION

We present a rare case of papillary thyroid microcarcinoma with contralateral lymphatic skip metastasis and breast cancer with supraclavicular lymphatic metastasis.

Core Tip: The recognized pattern of cervical lymph node metastasis (CLNM) of papillary thyroid carcinoma involves a stepwise route. Contralateral lymph node skip metastasis is very rare. In addition, the patient in our case report also suffered from a breast carcinoma accompanied by left supraclavicular lymphadenopathy, which made it difficult to distinguish the origin of the CLNM. Based on this case, we recommended that more detailed physical and imaging examinations are needed for patients with uncommon cervical lymphatic metastasis of primary cancer.
