Abstract

We report a case of a 23 year old Indonesian female patient who presenteded with foreign body sensation and dysphagia. She was found to have a left tonsillar polypoidal mass and a tonsillectomy was performed. The histopathology result came back as lymphangiomatous polyp. Tonsillar lymphangiomatous polyp is an uncommon hamartomatous lesion that generally arises from the tonsillar surface and it has rarely been reported in the medical literature, with only five reported cases in children and six in adults.

 

INTRODUCTION

Hamartomas are simple and spontaneous growths composed exclusively of components derived from local tissue. The growths produce an excessive number of cells that reach maturity and cease to reproduce, so the growth is self limiting. Hamartomas often present many clinical features of a neoplasm, although they are basically malformation1. Tonsillar lymphangiomatous polyp is a kind of hamartomatous lesion and it has been described by different nomenclatures such as lymphangiectatic fibrous polyp, polypoid lymphangioma of the tonsil, hamartomatous tonsillar polyp and so on2-5. The purpose of this paper to present a tonsillar lymphangiomatous polyp in a 23 year-old patient who had her symptoms of foreign body sensation and dysphagia for the last three years and yet the condition was still not diagnosed.

CASE REPORT

A 23-year-old Indonesian lady was seen in our ENT OPD with chief complaint of foreign body sensation and difficulty of swallowing of three years duration. However she was otherwise asymptomatic. She was not a smoker and was healthy with no previous surgery or treatment. The local physical examination revealed a pedunclated mass extending from the left palatine tonsil. There was no evidence of cervical lymphadenopathy. She underwent tonsillectomy. Grossly, there was a 1.9 X 1.1 cm sized polypoid mass attached to the left tonsil (Fig. 1) with slender stalk (Fig. 2); it was firm in consistency and appeared fibrotic.

Histologically, it was polypoidal lesion (Figure 3 ), lined by squamous epithelium (Figure 4), with underling inflamed core of  fibrous tissue, with dilated lymphatic vessel (Figure 5 ).

In the follow up period, the patient remained asymptomatic with no evidence of remnant or recurrence.

DISCUSSION

The head and neck is the most common anatomic region for lymphangiomatous lesions, accounting for over 90% of all lymphangiomas6. Most arise in the skin and subcutaneous tissues, but other sites include the larynx, parotid gland, mouth, and tongue7. The tonsil is less common site for the development of lymphangiomatous tumors. It contained the two  basic tissue types of the tonsil-lymphoid and epithelial-in the characteristic close anatomical relationship of tonsillar tissue, this feature supports the hypothesis that benign tumors of the tonsil may be hamartomas of the tonsil or bronchiogenic remnant rather than true neoplasms8. The pathologists have had difficulties in specifically classifying their cases and they have named them as fibrolipomas or have given them a more descriptive diagnosis, such as “ polypoid tumor containing fibroadipose tissue.”3 Clinical features are dysphagia, snoring, and the sensation of foreign body with insidious progression5. According to the size of the tumor, swallowing disorders, cough, aspiration and eructations can occur9.
Usually the morphological aspect of the tumor is similar to the one of a polypoid lesion attached to the tonsil, to the wall of the tonsillar bed, or to the lateral wall of the hypopharynx, pedunclated, with single or multiple lobulation, smooth surface and a bright red color or pink as the pharyngeal mucosa5. Kardon et al.4 reviewed 26 cases of lymphangiomatous polyps and they described the various histological features of the polyps. They were usually covered by squamous epithelium and showed variable degree of epithelial hyperplasia and proliferation of lympho-vascular channels, collagen, adipose tissue and lymphocytic infiltration were present in the stroma10.
Treatment is through surgical resection. Complete excision of the lesion including the stalk is usually successful. In adults, surgery can be performed under local anesthesia8. In the case of voluminous lesions of the pharynx or esophagus and/or in children, general anesthesia is preferred11. The tumor is grasped and tractioned to the oral cavity with a forceps for further clamping of its stalk and total excision12. Even for giant tumors, lateral pharyngotomy was hardly ever necessary13. In our case, because there was a history of recurrent episodes of tonsillitis, we choose to perform bilateral tonsillectomy.

CONCLUSION

Lymphangiomatous polyps of the tonsil are benign tumors that most frequently present as mass lesions and are composed dilated lymphatic channels and a fibrous, lymphoid and/or adipose stroma. They have varied histological features. Treatment is mainly by surgical excision of the mass alone or tonsillectomy, depending on the involvement of the surrounding tonsillar parenchyma or presence of recurrent episodes of tonsillitis. There is usually no recurrence according to the literature.
