Multiple linear eccrine spiradenomas with eyelid involvement

Adnexal neoplasms of the eye

Adnexal neoplasms of the eyelid encompass a wide variety of benign and malignant tumors of sebaceous, follicular, and sweat gland origin. Due to the specialized structures of the eyelid, these neoplasms present differently when compared with those of other locations. Although most dermatologists and ophthalmologists are familiar with the commonly reported adnexal tumors of the eyelid, such as hidrocystoma, pilomatrixoma, and sebaceous carcinoma, many other adnexal neoplasms have been reported at this unique anatomic site. Accurate and timely identification of these neoplasms is essential, as alterations of eyelid anatomy and function can have a negative impact on eye health, vision, and quality of life. We review the clinical and histopathologic features of common and rare eyelid adnexal neoplasms and discuss proposed treatment options.

Eccrine spiradenoma of eyelid - a rare tumor at an unusual location with literature review

Eccrine spiradenoma is a rare sweat gland tumor and usually presents as a solitary, painful nodule. A solitary spiradenoma involving the eyelid is quite rare. A 39-year-old Indian female presented with a gradually increasing, painless, nodular upper eyelid mass for the past 4 years. On examination, a non-tender approximately 4 × 3 mm cystic mass was noted, which was not adherent to underlying structures. The mass was excised in toto, and the histopathological examination was suggestive of eccrine spiradenoma with a low Ki-67 index. The patient was doing well without any signs of recurrence at 2 months of follow-up.

Acquired nasolacrimal duct obstruction: clinical and histological findings of 275 cases

Background

Acquired nasolacrimal duct obstruction is a blockage of the lacrimal outflow system usually caused by local nonspecific inflammation of the lacrimal sac and the nasolacrimal duct. However, cases exist where the primary nasolacrimal system obstruction is caused by malignancies.

Our aim was to investigate lacrimal sac pathologies in patients with acquired nasolacrimal duct obstruction and compare their clinical manifestations.

Methods

This retrospective clinical study included 275 patients with acquired nasolacrimal duct obstruction who underwent external dacryocystorhinostomy and lacrimal sac biopsy. Cases were classified into tumor or nonspecific pathology groups and subdivided according to the level of inflammation. Histological and clinical data were analyzed.

Results

Three tumors (1.1%) (an adenoid cystic carcinoma, an eccrine spiradenoma and small B cell lymphoma) were diagnosed. Chronic nongranulomatous inflammation was the most common histological finding, corresponding to 194 cases (70.5%). The other 81 (29.5%) were subacute, acute forms of nongranulomatous inflammation, tumors and fibrosis cases. Epiphora with continuous purulent discharge was the most common clinical sign reported by 144 (52.4%) patients, and two (0.7%) patients had a palpable mass near the medial canthal tendon, which was identified as an eccrine spiradenoma and small B cell lymphoma. There was no significant difference in the clinical symptoms, duration or case history between the nonspecific pathology and tumor groups (p = 0.292).

Conclusions

Chronic nongranulomatous inflammation of the lacrimal sac was the most common finding among acquired nasolacrimal duct obstruction cases. There were no associations between the histological findings and clinical presentation. The authors recommend a lacrimal sac biopsy only in cases when a tumor is clinically suspected.

Zosteriform spiradenoma with spiradenocarcinoma: A rare entity

Eccrine spiradenoma (ES) is an uncommon well-differentiated benign tumor originating from the sweat glands. It usually occurs as a single lesion in adults. Multiple ES in a linear or zosteriform distribution are rare. Spiradenomacarcinoma is an extremely rare tumor, which develops in an existing benign spiradenoma of several years of duration. We report a case of a 23-year-old- female patient with multiple spiradenomas arranged in zosteriform pattern and malignant transformation occurred in one of the lesions over a period of 10 years.

Inexplicable Co- Existence of Eccrine Spiradenoma and Lichen Planus in an old Case of Basal Cell Carcinoma

Eccrine spiradenoma is a rare benign adnexal tumour usually seen in the head, neck or upper trunk in young adults. It is rare in the lower extremities and in the elderly. Co- existence of eccrine spiradenoma with other lesions like cylindroma, trichoepithelioma, hidradenoma and chondroid syringoma has been documented in literature. But, concomitant occurrence of eccrine spiradenoma with a non- neoplastic lesion like lichen planus in an old and treated case of basal cell carcinoma has not been documented in literature till date. We present a rare case of eccrine spiradenoma occurring on the right thigh in an elderly female along with lichen planus over the left breast. The lady had been diagnosed with basal cell carcinoma 10 years ago and treated with wide local excision. A brief review of literature is also included.

Two Cases of Multiple Eccrine Spiradenoma with Linear or Localized Formation

We report two rare cases of recurrent, multiple eccrine spiradenoma. Both cases presented with extensive lesions comprised of multiple red papules of various sizes and a soft blue-red nodule. The first case was a 30-year-old woman. Her lesions followed a linear arrangement on her chin, and extended down the right side of the neck with spontaneous pain. The second case was a 57-year-old woman with tumors in a localized group on the left occipital region without pain. A search of the literature revealed only 15 reported cases of linear/zosteriform/nevoid multiple eccrine spiradenoma. Both cases were treated by surgical excision. Most of the red papules displayed typical histological features including two cell types: large clear cells with low-density cytoplasm; and small dark cells with high-density cytoplasm. The large soft tumors exhibited a variable histological appearance. In the first case, the cystic tumors displayed an homogeneous structure comprised of eosinophilic material. In the second case, the cystic tumors included abundant interstitial tissue.

Case of recurrence of spiradenoma in palpebral conjunctiva

Background

To report a rare case of a recurrence of spiradenoma that developed in the upper eyelid.

Case presentation

A 49-year-old woman who had a second recurrence of a tumor in the right palpebral conjunctiva underwent local resection of the lesion with adjunctive cryotherapy to the surgical site. The tumor consisted of smooth, round to oval nodular lesions approximately 1–3 mm in size with enlarged blood vessels. Histopathologically, the solid and well-circumscribed nodule was located beneath the conjunctival epithelium. It was composed of cells with slightly basophilic-to-clear cytoplasm and round-to-oval nuclei arranged in a trabecular pattern. Periodic acid-Schiff stain was positive in the cytoplasm, and the staining disappeared after digesting by diastase. Many cells in mitosis were observed throughout the tumor but no necrotic cells. Immunohistochemistry showed that the Ki-67 labeling index was 12%. From these findings, we diagnosed this tumor as a recurrence of the spiradenoma. There has been no recurrence and no signs of malignancy in the 6 months after the surgical excision.

Conclusion

Our findings indicate that a spiradenoma should be completely excised surgically because of malignant transformation after repeated recurrences.

Pediatric segmental eccrine spiradenomas: a case report and review of the literature

Eccrine spiradenoma is a rare benign adnexal tumor that usually occurs as a solitary nodule, although there are reports of multiple eccrine spiradenomas occurring in a segmental, linear, blaschkoid, or zosteriform pattern. Segmental eccrine spiradenomas have rarely been reported with onset occurring in childhood or adolescence. We describe a case of segmental eccrine spiradenomas occurring on the neck and mandible of a child.

Direct intracranial extension of malignant eccrine spiradenoma of the face

Malignant eccrine spiradenomas are exceedingly rare tumours. They are aggressive tumours normally arising in long-standing benign eccrine spiradenomas. We present a case of malignant eccrine spiradenoma of the right side of the face with direct intracranial extension without distant metastasis. A 48 years old woman presented with a large exophytic tumour on the right side of her face. Radiological imaging of the head and neck region revealed extensive invasion of the facial tissues around right orbit, maxilla and extension into the middle cranial fossa involving the right temporal lobe. She underwent craniotomy and debulking of the right temporal lobe and biopsy of the facial tumour. Histopathological findings were consistent with malignant eccrine spiradenoma. This is a rare case of facial malignant eccrine spiradenoma with direct intracranial extension with no distant metastasis. A literature search revealed that it is first case to be reported of this kind.

An unusual case of congenital linear eccrine spiradenoma

Eccrine spiradenoma (ES) is a benign uncommon tumor of skin adnexa with a characteristic clinical and histopathological presentation. Typically, it presents as a painful, slow growing and solitary nodule on the head or upper trunk in adult patients. We report a child with linear ES which presented with asymptomatic papulonodular lesions in a blaschkoid distribution on the face. Cases reported in the literature of multiple spiradenomas are very rare and multiple linear lesions are even rarer. To date, 21 cases of linear/multiple ES have been reported. Of these, eight were in children or adolescents. We report an additional case of this rare clinical presentation and review the literature.

[Multiple linear spiradenoma with a linear distribution]

We report the case of a 32-year old woman who presented with multiple nodules in the left arm and breast that had been present for 15 years. These nodules had a bluish colour and were occasionally painful. She had gone under excision of three other nodules on the left arm with the histopathological diagnosis of spiradenoma. All of the nodules were disposed in a linear arrangement and underneath a maculo-papular erythematous lesion which clinically seemed to be an epidermal nevus. The case described in the literature of multiple spiradenomas are very rare and multiple linear spiradenomas are even rarer.

Linear spiradenoma with focal malignant transformation

Malignant spiradenoma is an exceedingly rare adnexal tumour clinically characterized by rapid enlargement of a pre-existing, long-standing benign spiradenoma. Microscopic examination typically reveals a continuum between benign spiradenoma and areas of malignant transformation. Biological behaviour is unpredictable and it should be regarded as a potentially lethal neoplasm. Treatment recommendations require radical surgical excision. The reported case of a 23-year-old female illustrates the malignant transformation of a 1.5 cm nodule within a large linear spiradenoma almost covering the frontal aspect of the lower leg. In reviewing the literature, malignant transformation seems to occur slightly more often in multiple than in solitary spiradenomas. It is unclear whether excision restricted to the malignant area is an advisable treatment option in comparison to total excision of all spiradenoma nodules. In the presented case, the transformed area was excised. The patient is free of recurrence after 2 years.
