Dermatology Unit, Department of Medical, Surgical, and Neurological Sciences, University of Siena, 51300 Siena, Italy.
Background/objectives: Hidrocystomas, eccrine and apocrine, are rare cystic lesions that form benign tumors of the sweat glands. This study aimed to describe the clinical features of hidrocystomas and evaluate the role of non-invasive imaging techniques, including dermoscopy, Line-field Confocal Optical Coherence Tomography (LC-OCT), Reflectance Confocal Microscopy (RCM), and Ultra-High-Frequency Ultrasound (UHFUS), in their diagnosis.
Methods: In total, seven cases of hidrocystomas were collected from the Dermatologic Clinic of the University of Siena, Italy.
Collision of Basal Cell Carcinoma with Apocrine-Sebaceous-Follicular Unit Neoplasms.
Dermatopathology (Basel)
October 2024
Dermatology Department, Doctor Jose Molina Orosa Hospital of Lanzarote, 35500 Arrecife, Spain.
Article Synopsis
- Tumor collisions, a rare occurrence with a 0.0017% incidence rate, often involve seborrheic keratosis, melanocytic nevi, and basal cell carcinoma (BCC), and are generally considered incidental events.
- A retrospective study was conducted analyzing hospital records to identify collisions between BCCs or squamous cell carcinoma (SCC) and apocrine-sebaceous-follicular unit (ASFu) neoplasms from 2005 to 2017.
- The study identified 12 collision cases involving BCC and ASFu tumors, primarily in immunosuppressed patients, with many neoplasms located beneath the BCC, leading to new insights and hypotheses about these tumor interactions
Conjunctival Apocrine Hidrocystoma: A Case Report and Review of Literature.
Cornea
November 2024
Department of Ophthalmology and Visual Sciences, University of Michigan W.K. Kellogg Eye Center, Ann Arbor, MI; and.
Article Synopsis
- The study focuses on a case of conjunctival apocrine hidrocystoma that developed 60 years after a strabismus surgery in a 71-year-old man, highlighting its clinical features.
- The cystic lesion was diagnosed through surgical excision, revealing characteristic cell structures associated with apocrine hidrocystomas, and a review of seven similar cases found that all presented after age 50.
- The findings suggest that previous trauma or surgery, like strabismus surgery, might lead to the development of apocrine hidrocystomas due to ectopic gland deposition.

Rare Presentation of Apocrine Hidrocystoma Along the Nasolacrimal Duct.
Eplasty
December 2023
Department of Ophthalmology, All India Institute of Medical Sciences, Bhubaneswar, Odisha, India.
Article Synopsis
- Hidrocystomas are infrequent benign cystic tumors originating from sweat glands, and this case is unique as it involves the nasolacrimal duct, which has not been previously reported.
- A 28-year-old woman with no major medical history had a growing mass near her right lower eyelid for two years, leading to a CT scan that revealed soft tissue in the nasolacrimal duct.
- After surgically removing the cyst, the histopathological examination confirmed it was an apocrine hidrocystoma, highlighting its rarity.

Article Synopsis
- - Apocrine cystadenomas are uncommon benign tumors that can develop near the eyes, originating from glands of Moll, and are identifiable by specific histopathological features that set them apart from similar conditions like hidrocystomas.
- - A study analyzed four male patients aged 20 to 62, all initially misdiagnosed with hidrocystomas; upon surgical removal, histopathological evaluations confirmed apocrine cystadenomas without atypical or infiltrative traits.
- - These cysts can be mistaken for other skin lesions, particularly in the eyelid area, highlighting the need for awareness among ophthalmologists and recommending further research into their characteristics.
Apocrine cystadenoma: A long-standing apocrine hidrocystoma with an adenomatous proliferation.
J Cutan Pathol
March 2024
Department of Dermatology and Cutaneous Biology, Sidney Kimmel Medical College at Thomas Jefferson University, Philadelphia, Pennsylvania, USA.
Article Synopsis
- Apocrine cystadenoma is a rare, benign cystic tumor with unclear origins, linked to long-term apocrine hidrocystomas, and primarily occurs on the scalp of older adults.
- A study analyzed 13 cases revealing they typically presented as slow-growing, multilocular lesions with distinct dermatoscopic features, including a range of colors and prominent peripheral vessels.
- Histologically, the tumors displayed a mix of nonproliferative apocrine lining and proliferative adenomatous components, with specific immunohistochemical staining patterns noted, but findings are limited by the study's single-institution, retrospective design.
Orbital apocrine hidrocystoma. Report of two cases.
Eur J Ophthalmol
May 2024
Orbital and Adnexal Service, Tiberia Hospital - GVM Care & Research, Rome, Italy.
Article Synopsis
- Two cases of orbital hidrocystoma are reported, highlighting clinical features and management strategies for an enlarging orbital mass.
- One patient was a 48-year-old man with a mass near the supraorbital area, and the other was a 70-year-old man with a lesion near the lacrimal gland; both diagnoses were confirmed as apocrine hidrocystomas through histopathology.
- Post-surgery, mild nerve sensation loss in the first patient resolved quickly, and no recurrences were observed in either case during follow-up; these findings suggest that apocrine hidrocystomas, though rare in the orbit, should be included in the differential diagnosis for similar cystic masses.

Cutaneous Neuroendocrine Mucinous Carcinomas Are Low-grade But May Be Associated With Other Cancers.
Am J Surg Pathol
October 2023
Department of Pathology and Laboratory Medicine, Memorial Sloan Kettering Cancer Center, New York, NY.
Article Synopsis
- The study investigates the relationship between the presence of neuroendocrine marker INSM1 in cutaneous mucinous sweat gland carcinoma and its implications for patient prognosis, based on newly developed staining techniques.
- Out of 12 adenocarcinoma cases, most mucinous types were found to express INSM1, which was associated with lower risk of metastasis, while nonmucinous cases showed higher potential for lymph node involvement.
- The findings suggest that routine testing for INSM1 in skin tumors could improve patient screening and follow-up, as those with neuroendocrine tumors may have different cancer risks compared to non-neuroendocrine types.

Apocrine Papillary Hidrocystoma With Mucinous Metaplasia (Goblet Cell Type): A Case Report and Review of the Literature.
Am J Dermatopathol
May 2023
Department of Cleveland Clinic, Pathology and Dermatology Institute, Cleveland, OH.
Article Synopsis
- Mucinous metaplasia, specifically the goblet cell type, is extremely rare in the skin, and this case report discusses the second occurrence involving an apocrine papillary hidrocystoma.

Median raphe cysts: A clinico-pathologic and immunohistochemical study of 52 cases.
J Cutan Pathol
June 2023
Department of Dermatology, Fundación Jiménez Díaz, Universidad Autónoma, Madrid, Spain.
Article Synopsis
- - Median raphe cysts (MRC) are non-communicating cystic lesions in the genital area, showing positivity for various immunohistochemical markers including CK5-6, CK7, and p63.
- - A study of 52 patients over 26 years employed monoclonal antibodies to investigate these markers, revealing significant expression of GATA3 and CK7 among the cases.
- - Findings suggest MRC may originate from urothelial cells, and no significant differences were observed between HMFG1 expression in MRC and apocrine hidrocystomas.
